+++ This bug was initially created as a clone of Bug #926522 +++
A lighter weight test is
1. Load http://dev.noteflight.com/scores/view/66d71f5197498141dc00d01fffed1d383795fa61?app=html5
2. Click "Listen".
3. Wait for playing to start.
4. Quit.
Expected results:
shutdown quickly
Actual results:
shutdown takes longer than 30 seconds.
What I think is the best solution is in bug 926522 and bug 928222, but those
are fairly complex changes.
The purpose of this bug is merely to undo the regression from
http://hg.mozilla.org/mozilla-central/rev/8edc48525bc6
with a changeset that is suitable for branch uplift.

This happens to work because the window is closed before nsThreadManager is
shutdown. It also doesn't prevent the same bug happening if a decode task is
run after the window is closed, but solves the bug in the same cases as before
8edc48525bc6 landed. The destructor would be nice place to put this, but that
doesn't run until after nsThreadManager shutdown.

prevent MediaBufferDecoder threads from waiting after AudioContext shutdown
[Approval Request Comment]
Bug caused by (feature/regressing bug #): regression from bug 914030 in the new Web Audio decodeAudioData() method.
User impact if declined: slow shutdown sometimes
Testing completed (on m-c, etc.): on m-c
Risk to taking this patch (and alternatives if risky): the patch is small, intended for minimum risk, and risk is confined to web audio.
String or IDL/UUID changes made by this patch: none.

The link from comment 0 is no longer available for testing (Page not found). Is there any other link that I could test with?
I've tested with the link from bug 926522 comment 0 and no 1 minute hangs encountered on latest Aurora 28.0a2 (Build ID: 20131212004008), the shutdown takes about 3 seconds.

is simliar, but heavier.
Wait for the score editor to load and set up.
Click "Listen".
wait for 1 sound to load and quit.
