Comment(by kcrisman):
To release manager: This should probably be marked Invalid or Wontfix.
The Pynac switch has massively sped up assumptions, so that the timing
above that was 2.91 s is now about 0.02 s, presumably on a fairly similar
machine. In addition, the fix indicated by was is no longer correct (if
it ever was), because although maxima.eval is indeed faster, it needs to
have a string passed in, not a string evaluated at a SymbolicExpression...
Anyway, the proof is in the pudding: with 4.1.1, both with and without the
appropriate version of the proposed change, assume(x>0) requires 33
microseconds. Since that is already 1000 times faster than the fastest
time above, we probably don't need to worry about this any more.
