Otherwise when running -386 and -amd64 on the same machine
with both copies of TDM-GCC installed (the installer wizard lets
you choose which one, and you can do both options in two
different install attemps), one previously got this error when
using the 64-bit gcc with a 386 build:

Creating a new disk is the major latency cost of creating a
new instance. If we reuse a previous disk image, the VM and
CoreOS boot much quicker and start building again.
So add a mode where we don't mark the disk as delete-on-death
when we create it, and we search for a suitably-named existing
one on creation and try to reuse it.
It's a cache, essentially. It's still stateless.

Then make the coordinator and linux environment Makefiles have
an upload target. Amusingly, this actually worked: the Docker
images now tar + compress + upload over HTTP all in a stream,
without even knowing how large the resulting tar.gz will be until
it's done uploading.

They were from a time before we had the os/exec package, if
memory serves.
Also, make verbose also mean that the main build's stdout
and stderr go to the real stdout and stderr as well.
I'll want that for the Docker-based builder.

Good checkpoint. Can now do builds by hand.
Next step is coordinator server in front of this, and things
to fire up beefy GCE instances running CoreOS and each build
in its own Docker container. See README for how to do a single
build.

Currently for every benchmark/metric we show all changes for all builders x procs.
With 4 builders and 5 procs, that's 20 changes (20 red/green boxes in a single cell).
Instead show only maximum change for every benchmark/metric.
This significantly reduces clutter in UI.
When you click on the red/green box, you can see the rest of the changes.

Currently we still see some flakes on perf dashboard (e.g. sys-stack is quite frequent).
I am planning to run real perf builder with 5 different values of GOMAXPROCS,
so we can require 3 builders to agree on a change instead of 2.
This will provide 20x improvement in flake detection.
At the same time lower noise bar from 1.2 to 1.1, as I see some real perf changes gets ignored as noise.
All these magic numbers affect only representation of data, but not the data stored in DB.
So we can continue freely tuning them later. There are no significant risks here.

original value. Windows might use either for the sub-process.

1) Killing proceses on timeout was wrong: the os/exec
package will never return our package's error type
from its Wait.
2) fix a goroutine leak on timeout.
3) unexported an undocumented and elsewhere-unused type.
4) rename timeout type to end in "Error", per convention,
not Err.

If we are building, for example, linux/386 on a linux/amd64 machine we want to make sure that the whole build is done as a if this were compiled on a real linux/386 machine. In other words, we want to not do a cross compilation build.
The exception to this rule is when we are doing nacl builds. These are by definition always cross compilation, and we have support built into cmd/go to be able to handle this case.
