<span class="quote">> Hm. Probably none.</span >
Actually, I think there are: E.g. consider one thread calling glClientWaitSync
with a non-0 timeout, blocking for some time with the mutex locked. If another
thread calls glClientWaitSync with a 0 timeout (or whichever API call ends up
in st_check_sync) during that time, it'll block until the first thread unlocks
the mutex.</pre>
