This is a spin-off from bug 1054011 comment 12.

STR:
Tap application icons fast/randomly to launch multiple apps at the same time.

Actual Results:
Screen stays at app splash screen. Cards view has two apps "Template" and "IME Tests", but b2g-ps lists only "Template":

Expected Results:
Preallocated process should become the app.

Repro Rate:
< 10%

Notes:
It is process 6542 the "IME Tests", backtrace shows epoll_wait() in nsAppShell::ProcessNextNativeEvent().
