While running A/V Pairtree in production for the first time, I observed that the
audiowaveformprocesses were getting stuck in the "interruptible sleep" state. I determined that they were simply waiting for I/O to complete (i.e., for their output to be read by the parent process); from the docs:I guess this is why. Interestingly, the automated tests didn't catch this -- anyone have an idea why?
Anyway, I've manually tested this change locally and on our "prod" machine, and can confirm that it actually works now.
Also, the debug logging is a bit more verbose now (stderr provides interesting stats about the audiowaveform conversion).
