     1 A word to the wise:

     3 You must ensure that if your test finishes successfully, no processes have

     4 priority FOREGROUND_HIGH.

     6 If you don't do this, expect to see tests randomly fail with mysterious

     7 FOREGROUND --> FOREGROUND priority transitions.

     9 What's happening in this case is that your FOREGROUND_HIGH process lives until

    10 the beginning of the next test.  This causes the process started by the next

    11 test to have low CPU priority.  Then the FOREGROUND_HIGH process dies, because

    12 its iframe gets GC'ed, and we transition the new test's process from low CPU

    13 priority to regular CPU priority.

    15 Ouch.
