It looks like we don't need to watch for hanging writes now that we're using the callback mechanism.

We can sometimes get into a state where AAudioStream_write() will just block forever until we pause and unpause.
None of the standard state queries indicate any problem in my testing. And the error callback doesn't actually get called.
But, AAudioStream_getTimestamp() does return AAUDIO_ERROR_INVALID_STATE
