Well, okay.  But the fact was not widely known and the 3.0 release
appeared more or less out of the nowhere.

Not possible.  The lockable memory is very limited and thus it was not
that somple.  Please check the code to see what I did to keep the amount
of locked memory at a minimum.

I know x86 well enough to check whether SSE is used or not.

2.0.2 does not.  Or what file did I missed?

I never complained about current versions of GMP and 2.0.2 was very fine
code at its time.
