<!--
A simple test of the process priority manager.
https://bugzilla.mozilla.org/show_bug.cgi?id=844323
Note: If you run this test alone (i.e. not as part of the larger mochitest
suite), you may see some IPC assertions, e.g. "Can't allocate graphics
resources."
What appears to be happening is that we close the Firefox window before the
frame we create in this tab finishes starting up. Then the frame finishes
loading, and it tries to show itself. But it's too late to show a remote frame
at that point, so we kill the child process.
In other words, I think these errors are nothing to worry about.
