python threading limited to 1 or 2 cores

[Kevin Abbey]

  Hi,

I've discovered from a user I support that the python in fedora 13 does 
not use all cores with the threading module but when the python source 
is complied and installed with default options then all cores are used.

Can someone explain why this is happening?
Is there a setting to allow users to use all cores?  The server has 48 
cores and many others have 8 or 16.

Thank you,
Kevin
