Changing the summary like that means that tbpl will never ever again find this bug for any failure in any test. Was that your plan?
Does this mean that a child process is dying, or that the parent process is dying?
(In reply to Phil Ringnalda (:philor) from comment #4)
> Was that your plan?

Nope.
 
I changed it because names of the recent failures didn't fit in the summary (since these test names are huge), but they seemed to be due to this bug. (And I thought TBPL's fuzzy-matching might apply to the test-names, like it does for error messages).  If the test name needs to match exactly, then I suppose we can file separate bugs for separate tests (or separate chunks of tests).
(For now, I'll just revert my bug-summary tweak, and mention "test_browserElement_oop_*.html" to indicate (to humans) that this affects lots of tests whose names match that pattern.)

https://bugzilla.mozilla.org/buglist.cgi?quicksearch=test_browserElement_oop%2020%20kw%3Aintermittent - we have a *lot* of others that still have room left for another test name or two in the summary :)
I think essentially everything is going right here.  The child process's channel is closed, so it kills itself.

So offhand, I'd say we should exit(0) instead of exit(-20)'ing.  Let's see how bent feels about a patch.

I misunderstood.  The child is _exit(0)'ing, and that's somehow causing the parent to crash with code -20.
