something like:
cdef class GapElement(RingElement):
....
# include setjmp C header
....
cdef static jmp_buf buf
cpdef RingElement _div_(self, RingElement right):
if not setjmp(buf): #
return make_GapElement(QUO(self.value,
(<GapElement>right).value))
else:
raise #?????
Here QUO is a call to division done by the GAP interpreter wrapped
into a dynamic library.
In the latter I'd put the appropriate longjmp call, to deal with the
case of an error (e.g. zero division).

see above. Does it look right? Does it need sig_on(), etc?
