Python speed on Solaris 10

Since my post I have compiled Python 2.4.3 with Sun Studio 11 with 
"-fast" option (on Solaris 10) which has produced the fastest version of 
Python I've been able to test on this hardware, including the CentOS 
Linux version (which I'm pleased about).

I haven't looked into more optimal gcc build options yet, so that may 
produce a faster build, but I am probably satisfied with what Sun Studio 
has given me for now.
