Assume Process::CLOCK_MONOTONIC exists (possibly emulated) and
there is no need to bloat our code by defining a compatibility
constant.
* lib/benchmark.rb: just use Process::CLOCK_MONOTONIC

In addition to being unaffected by _offset_ correction,
CLOCK_MONOTONIC_RAW is also unaffected by _frequency_ correction,
making it unsuitable for measuring real time on systems where the
clock is always running too fast or slow.
CLOCK_MONOTONIC (without _RAW) is the correct clock, as it is unaffected
by _offset_ correction (due to human error or battery replacement), but
still takes _frequency_ correction into account for clocks which
consistently run too fast or slow.
Thanks to Vít Ondruch for reporting the issue on ARM [Bug #10202]

is not supported on old linux.

if available to more accurate measure.

patched by Benoit Daloze. [ruby-core:37593] [Bug #4940]
* lib/benchmark (Benchmark#bmbm): bmbm should be consistent with bm
for the return value.
* test/benchmark: remove preemptive test instead of skipping
I removed the preemptive test I wrote for Feature #4197.
I'll add it back when the implementation will be able to satisfy it.
* lib/benchmark (Benchmark#bmbm): remove useless explicit call,
#format is an alias of #to_s test/benchmark: add a test for
format of long time.
* lib/benchmark: fix label width: always add 1 to ensure there is a
space delimiter even with times over 100s
When I asked for Feature #4197, I wanted to make delimiting spaces
consistent for #bm and #bmbm.
But with times over 100s, the output contains no space between the
label and the first time (user).
Now both ensure there is always a space, even if that means 3 spaces
with times under 10s (because it is formatted as %10.6f)
* test/benchmark: let labels be a constant
lib/benchmark (Benchmark#realtime): avoid creating an unused Proc
lib/benchmark (Benchmark#benchmark): use ensure clause to restore
STDOUT.sync, as in #bmbm
