Oh, I completely agree with you.   But sometimes, you just
forget where the boundaries are in your application code,
and well, then . . . . .

My error that caused the deadlock was certainly something
I never should have done, but it (as always) happened so
rarely that it was hard to replicate (and in some cases,
hard to notice, as it only locked two threads out of many).

Likewise:  I wouldn't run my application with STL iterator
debugging enabled, but it's great during development for
those occasional brain farts.
