Youve got 80 threads? thats crazy, unless:
* you are running on a 40 cpu smp system
* you have need to perform some off-box request (oracle query, perhaps) o=
nto
  something with nearly that many cpus.

If you come from an apache background and your intuition tells you that y=
ou=20
need that many threads, then your intuition is wrong.
