Done.

I found some additional lock-handling problems.  I added simple fixes 
for them, but the right thing to do is to create a lock class that you 
can instantiate on the stack on entry to the function so that it is 
always destroyed correctly on function exit.  I've added this to the 
Wishlist.

Accepted, with minor changes.  Thanks!
