Subject: Remove an extraneous mutex unlock.
X-Git-Url: http://git.vrable.net/?p=bluesky.git;a=commitdiff_plain;h=90e223dd5f5eeb9c87a6c5764b706a87695ec964

Remove an extraneous mutex unlock.

I'm surprised that this didn't cause trouble earlier; it seems that
unlocking an unlocked mutex raises no errors (but under heavy load, when
the mutex is locked by another thread then unlocking it can cause trouble).
