Python threading, and processes

[Robin Haswell]

Hey there

I'm doing some threading in python with Python 2.3 and 2.4 on Ubuntu and
Debian machines, and I've noticed that if I open a lot of threads (say,
50), I get lots of python processes with individual PIDs, which consume a
disproportionate amount of CPU. Does this mean that Python is using the
dummy_thread module by accident? And is there a realistic limitation to
the number of threads I can do?

Cheers
