[x264-devel] Yet another slicetype patch

[Mike Kazmier]

> After there was much discussion around the use of usleep in the patch, it has been removed and the patch solely relies on pthread_cond_wait/broadcast now.  I understand there are still issues with Windows builds, but all tests on Linux have proved successful.

So after doing some more testing I am seeing a huge performance penalty with this patch versus the previous v9 patch (which had the usleeps).  Can anyone determine why.  This patch is only a few % faster than r1114 without the patch.
