Cross Product Results

I noticed an interesting artifact that is probably very old.
The cross product defin in OCTAVE-SHAR/m/linear-algebra/cross.m
return singular matrix errors if parallel vectors are used. Since
crossing vectors to find if they are parallel is not so uncommon,
this is inconvenient.

Is the tricky matrix determinant stuff done for speed, to keep all
the addressing out of the interpreter?
