threads do not necessarily slow you down much, after importing the
thread module python only slows down by about 50% and if the number of
threads is not large, the resource overhead is not too bad either.
there are much better reasons to avoid threads than efficiency, such
as error proneness and debugging difficulties due to nondeterministic
worrying about the global interpreter lock suggests you may be
planning to use multiple processors. in that case you need to use a
python process per processor.
