987164 - Sometimes the preallocated process isn't shut down and caused mochitest-2 timeout

Status: RESOLVED INCOMPLETE

(Core :: IPC, defect)

Description

[Cervantes Yu [:cyu] [:cervantes]]

Forked from bug 968604. test_Preallocated.html is not really shutting down the prealloc'd process. See https://bugzilla.mozilla.org/show_bug.cgi?id=968604#c14 for analysis.

Shutting down the test case async reveals another problem: the preallocated process seems not dying after we Close() it. See https://tbpl.mozilla.org/?tree=Try&rev=5d82ded68f39. We need to fix this.

Shutdown failure was fixed in bug 933680.

This recent push passed several consecutive runs. https://tbpl.mozilla.org/?tree=Try&rev=db068131b72f

And reverting the change brings the failure back: https://tbpl.mozilla.org/?tree=Try&rev=b95fd3e6bfec

We can add the test case back now.

I was wrong. The test suite is failing again. I will continue debug the failure.
