That just hasn't happened to me yet, at least in terms of program
organization.  Python threads get too slow once there are too many
tasks, but that's just an implementation artifact of Python threads, and
goes along with Python being slow in general.  Write threaded code in
GHC or Erlang or maybe Go, and you can handle millions of connections,
as the threads are in userspace and are very lightweight and fast.
