MultiprocessMessagePipeTest.MoreChildToChildPipes flakes due to timeout waiting for child process to exit

Project Member Reported by w...@chromium.org, Feb 22 2018 
Under Fuchsia/x64/Debug this flaked in https://ci.chromium.org/buildbot/chromium.fyi/Fuchsia%20(dbg)/16506 with a timeout:

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/92a8cd0fa676e90318fca3b78871477dc0448e61

commit 92a8cd0fa676e90318fca3b78871477dc0448e61
Author: Wez <wez@chromium.org>

Filter all TaskSchedulerWorkerPoolBlockingTests which wait on capacity.

Several of these tests wait until the worker pool's capacity reaches an
expected value, which appears not to be a deterministic operation, and
fails often on the Fuchsia bots.

Also adds a filter for a flaking Mojo system unit-test.

This is flaky on Android.

[9 out of 46 builds have failed]
https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/KitKat%20Phone%20Tester%20%28dbg%29

Example:
https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/KitKat%20Phone%20Tester%20%28dbg%29/10365

+owner rockot@. Could you please take a look?
I am not sure this test is flaky for known reasons [comment 1] or if there is something unknown here.

+CC wez@, scottmg@ FYI.

Comment 6 by perezju@chromium.org, Dec 20 

Is this bug still relevant? Can't find the bot in #0 or new failures in the bot mentioned in #14.

Comment 7 by w...@chromium.org, Jan 2 

Re #6: The Fuchsia Debug bot is at https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/fuchsia-fyi-x64-dbg

AFAIK we're now running MoreChildToChildPipes on Fuchsia without issues, so I'm inclined to close this out and open a separate bug, if necessary, for the Android flakes.
