Sure, and I might do just that later. However, the PRNG in scipy really
needs to be updated before Python 2.5 will be released or widely adopted.

In any case, the amount of code duplication is small, just the MT19937
algorithm and initialization code which is tiny and from the same
reference implementation. I don't think anyone would derive much benefit
from our using the exported version.
