Ah, that makes more sense.

Yes.

Lets make things clear - a blocking can only happen in two cases:
The "normal" case involves VLC reading from a special file, e.g. a file on
a dead network share, a named pipe with only dead writers, a socket (but
not on Windows really), or a device file (e.g. CON, LPT1, COM1...).

If you see this with a local file, then you are in the abnormal case: your
operating system is just buggy and got stuck in a file system transaction,
or your hardware is failing.

But it might also simply be that VLC is stuck in *another* thread. In other
words, the stack trace is correct as such, but it does not show the correct
thread.
