How often should it be mentioned?  I mentioned it twice
early this month.  The previous mentions were in August,
then April, then January, then ...

Huh.  But I see I mention it the most, so I'm biased.

The major problem I have with it is its use of Intel
specific assembly, generated (I as I recall) through
gcc-specific inline code.  I run OS X.

So the only people who would use it are Python developers
running on a multi-proc Intel machine with Linux/*BSD
who have compute intensive jobs and aren't interested
in portability.  And don't prefer the dozen+ other more
mature/robust solutions.

I suspect that might be a small number.
