See [John Ousterhout]'s homepage for the Powerpoint slides of his talk
''Why Threads Are A Bad Idea (for most purposes)''.

Threading is "fault-prone, deadlock-prone, priority-inversion-prone".
Lock (mis)management makes it poor in scaling.  It's hard to reason
about thread behavior [[justify]].

[DKF] wrote in [the comp.lang.tcl newsgroup]: 
"When I deal with threading, I work on the principle that the hardware and OS are
my enemies and hate me, and so I code accordingly.  It probably doesn't make for
a maximally-efficient program, but it does reduce debugging pain."
