Description

[Lars T Hansen [:lth] (OOO until 12 August)]

All TypedArray jsapi-test tests currently work with ArrayBuffer.  Clearly we need to do better once TypedArray can map SharedArrayBuffer.

The "p" failure in that run is bug 1230162, technically a problem with running tests in parallel but fundamentally we should also clean up SpiderMonkey.

please wrap this line into 99 chars ;)
(or maybe there's different style rule for test files?)

":" should be aligned to the same column as "S" of "Shared ?" in previous line.

as "Shared" is now variable, using CHECK might be better for testing purpose here, and following several places.
