499644 - Intermittent leak of nsRunnable and nsBaseAppShell shown when running the IMAP xpcshell-tests

Status: RESOLVED FIXED

(MailNews Core :: Networking: IMAP, defect)

Description

Now that we've fixed other tests/leaks, we can clearly see the following leak when running the IMAP xpcshell-tests:

This leak is intermittent, but frequent. From when I looked at this before, it could be to do with how we're shutting down the IMAP thread - alternately it could be that we need to give the IMAP thread a little time to shutdown before we exit the tests.

I've just seen bug 472773 go in on branch. I've checked the tinderbox logs and done some runs of my own, and we should be clear of this now (I think it was probably only ever a mac bug).

Therefore marking fixed by bug 472773.
