Yep, I definitely think you're right. I had the same idea a little while ago, and I'm
glad that
at least I'm not so stupid that it didn't hit me eventually. I now feel confident
sending my
friend an update, thanks to your letter (I don't have a Linux machine to test on right
now). I
didn't know that use of "lock" translates to the same code as Monitor calls, but
thanks very much
for the information. I apologize for wasting people's time! I will think a lot
harder next time,
and not mix the calls
