Threading on Fedora Core

I've written some code that supports threads.  It's possible that there is
an issue in the code that causes a mutex to be blocked, or there might be
busy waiting threads.  Neither case is good.  Do you have the code in
question?

How many processors on the system, and what type?

It's unlikely an issue with Fedora Core, and more likely an issue with the
code.
