It would also make sense to add a "strict" keyword to header functions,
to turn toggle FITS conformance testing (or exceptions).  I haven't had
a chance to use pyfits yet (mainly due to poor performance of numarray
with small arrays... is this still a problem, by the way?), but this
makes me wonder if there already are fits conformance exceptions.
