I don't get that.  Phyton was never designed to be a high performance
language, so why add complexity to its implementation by giving it
high-performance capabilities like SMP?  You can probably get a bigger speed
improvement for most tasks by writing them in C than by running them on 2
processors in an inerpreted language.

Instead of trying to make Python into a high-performance language,  why not
try to factor out the smallest possible subset of the program that really
needs the performance boost, write that as a library in C, then put all the
high-level control logic, UI, etc. in Python?  The C code can then use threads
and forks if need be to benefit from SMP.
