No need to use synchro primitives like locks?

I know that it may work, but that strikes me as somehow wrong... I'm 
used to using things like Lock().acquire() and Lock().release() when 
accessing shared data structures, whatever they are.

Although trying to do the "right thing" may indeed get one in trouble in 
case of deadlock caused by a bug in one's own program.
