<!--
|
||||
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.
