Is any part of the patch going to be applied? I mentioned this problem in September last year and it looks like it's existed for years (the semaphore locking did the same thing).

Assuming that the rest of the patch is OK, shouldn't this be a
mutex_lock(), too, if the return value will be ignored?

Argh. Sorry, I accidentally reverted my changes and quickly went through them all again so yes, it should have been mutex_lock(). I should now change that on my running copy... which has somehow kept working.

Regards,
Andreas
