A lot of our thread pools use the default stack size for the platform
they're on, which can be rather large (8MB, usually, on Linux and OS X)
and is probably too much for the typical thread in the thread pool
regardless. SharedThreadPool already has some logic for selecting a
reasonable stack size for worker threads; let's move that logic to
nsIThreadManager so that logic (and constant) can be shared more
broadly. (That we already have a couple of instances of
SharedThreadPool usage solely for this constant suggests that it is a
concept that should be available in a more central location.)
Currently nsIThreadManager::spinEventLoopUntil doesn't monitor the shutting
down. Firefox shutting down can be blocked by a 'broken' use of
nsIThreadManager::spinEventLoopUntil.
nsIThreadManager::spinEventLoopUntilOrShutdown should be used instead.
The test helper_touch_action_regions.html uses nsDOMWindowUtils to synthesize native input events and creates some runnables to trigger the test. It expects the runnables which synthesize native input events are processed first, then the runnables to continue the test, and finally the input events are forwarded from chrome process to content process. Enabling event prioritization may change the execution order.
Wraps those runnables to synthesize native input events as priority=input and dispatches those runnables to continue the test with priority=input to make sure the execution order is as expected.

A number of places in JS need to drain the current thread's event queue,
which cannot be done with nsIThreadManager::spinEventLoopUntil, since we
need to not wait for an incoming event when attempting to process one.
The point of this exercise is to make the thread name available in the thread
func of the thread, so that we can register the thread with the profiler from
the very start of its lifetime, and so that registration and unregistration
can be inside the same function.
