Re: Proposal for fixing race conditions

There's another issue related to "live" Float32Arrays: developers neutering
arrays themselves. Developers can pass a Float32Array's ArrayBuffer to
postMessage as a Transferable, which neuters the array. What happens if
they do that to one of the arrays returned by AudioBuffer.getChannelData()
--- while the AudioBuffer is being played? If audio processing is using the
same underlying data as the Float32Array, I'm guessing the answer is
"something bad".

The spec needs to say whether or how neutering a Float32Array affects usage
of the ArrayBuffer. With my proposal, I would say that when we do an
"acquire AudioBuffer contents" operation, if any of the Float32Arrays are
neutered, then the acquired contents are treated as an AudioBuffer of
length zero.
