I'm still debugging this (although I have higher priority tasks to worry
about, unfortunately), but it appears that the mutex is already taken when
that code is executed. Unfortunately, I have been unable to figure out
where. One second the 'count' value is 1, and then it suddenly becomes
'0', and then mutex_lock() is called.
