There's no good reason why these can't be code constants.
Especially given that, due to a bug, changes to the
"idle_queue.{min,long}_period" constants were not being passed onto the C++
code!
Here's why: those two prefs were specified as integers in all.js. But we used
AddFloatVarCache() to set up the reading of those prefs. libpref fakes floats
by storing them as strings and then converting them to floats when they are
read.
Which means that AddFloatVarCache() used to fail to get the value from all.js
-- because there's a type mismatch, int vs. string -- and instead use the
fallback default. That value is the same as the one in all.js, which is lucky.
But if someone changed the value in about:config to 100 (an integer), a similar
failure would have occured and the value used by the C++ code wouldn't be
updated!
Also note that idle_queue.max_timer_thread_bound did not have a value in
all.js.
What a mess!

We can save the entry in the hashtable, and then re-use that entry as a
starting point for removing from the hashtable, should that become
necessary. This saves us having to rehash things, at a minimum.
Defining Get() in the declaration of InputEventStatistics implicitly
sticks an "inline" on the function, which is not what we want: inlining
it spreads around a lot of static initialization code. Providing an
out-of-line definition is much better in terms of code size.
We were extracting elements from the queue and unnecessarily refcounting
them, rather than transferring the owning reference out of the queue and
out to the caller.
This lets us replace moz_xstrdup() of string literals with AssignLiteral(),
among other improvements.

This also fixes the Unix part of bug 678369, and fixes bug 147659 as a
convenient side-effect of using LaunchApp (which has the desired
fd-closing behavior already) rather than directly using fork/exec.
The main goal is to work around bug 227246, where PR_CreateProcess on
Unix interferes with anything else that tries to use child processes.
This does not fix that bug -- NSPR will still cause problems if used in
that way -- but it's an adequate workaround for that bug in Gecko in
almost all cases (the one known exception is nsAuthSambaNTLM, which uses
NSPR directly and needs to be fixed separately).
Waiting for the child process uses waitpid() directly, sharing the
existing code used for OS X.

We were using a StaticRefPtr without it being fully defined for
SystemGroupImpl::sSingleton, resulting in a non-unified build failure.

Currently the Gecko Profiler defines a moderate amount of stuff when
MOZ_GECKO_PROFILER is undefined. It also #includes various headers, including
JS ones. This is making it difficult to separate Gecko's media stack for
inclusion in Servo.
This patch greatly simplifies how things are exposed. The starting point is:
- GeckoProfiler.h can be #included unconditionally;
- everything else from the profiler must be guarded by MOZ_GECKO_PROFILER.
In practice this introduces way too many #ifdefs, so the patch loosens it by
adding no-op macros for a number of the most common operations.
The net result is that #ifdefs and macros are used a bit more, but almost
nothing is exposed in non-MOZ_GECKO_PROFILER builds (including
ProfilerMarkerPayload.h and GeckoProfiler.h), and understanding what is exposed
is much simpler than before.
Note also that in BHR, ThreadStackHelper is now entirely absent in
non-MOZ_GECKO_PROFILER builds.
This adds an attribute 'noShell' to nsIProcess that is used to launch a process
using CreateProcess() if we are sure we are launching an executable and don't
require the extra work of the Windows shell service.
