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.
