For some reason this test is unreliable running on a VM, it fails intermittently like so:

*** 13276 ERROR TEST-UNEXPECTED-FAIL | /tests/docshell/test/navigation/test_not-opener.html | Should not be able to navigate popup's popup by calling window.open. - got 1, expected 2
*** 13277 ERROR TEST-UNEXPECTED-FAIL | /tests/docshell/test/navigation/test_not-opener.html | Should not be able to navigate popup's popup by submitting form. - got 1, expected 2
*** 13278 ERROR TEST-UNEXPECTED-FAIL | /tests/docshell/test/navigation/test_not-opener.html | Should not be able to navigate popup's popup by targeted hyperlink. - got 1, expected 2

Colin, could you provide some insight as to why the test would fail in this manner? We've seen that a lot of timing-related assumptions fail when running unittests in a VM, but I don't understand this test well enough to see what's happening. If need be, we can check in some debug log statements in the test to help track it down.

Sounds like the VM is slow and triggering a race condition.  I'm out of the country, but when I get back I'll try to figure out if this is a race in the test or not.  Any ideas how to debug this beyond staring at the code?
We can check in dump statements to do printf-style debugging if you'd like. Sprinkle them liberally to figure out what's going on, then we'll remove them when we fix it.

+/- related: same file, different error.
Adam says these are both the same bug in the test.
