I don't think that many threads are going to help you in any meaningful way. Especially
with Python's GIL. Can't you redesign your program to use a fixed number of threads such
as 1 per cpu core?

Or check out the multiprocessing module.

But yeah, I think your OS is preventing you from creating more threads (either due to
some artificial limit or due to lack of system memory).
