Good work Dave!
(a) don't commit to CVS until I have warned the postgis-users that we 
are about to make the CVS tree unstable
(b) you should be able to do isValid as well, I think Yury noted that 
as debugged in his last CVS commit
(c) I think a couple of the operators are done too (difference?) Yury 
can confirm
