I added some debug here and this never happens when playing some h264 file.
In fact I wouldn't even know how to have a thread terminate immediately
after creation before the parent sees _beginthreadex returning.
Of course I can add more ifdef but that'd make the code more ugly to
prevent something that is quite unlikely to *ever* happen. If by misluck
it still happened then yeah the error (because such a quick return would
likely be an error) would take a few more nanoseconds before the thread
This code only runs on cleanup of detached threads and there's only 2 of
them: playlist preparser and fetcher. Both have no possible error case
and will end only after all items have been preparsed.
Is there still some problem that I missed?
