All tests eventually pass on modular/abvar/homspace.py, seems to be a serious speed regression.

Hmm... apparently this isn't new.

Re the timings, I was testing with the refnanny enabled.

- Resolution set to fixed
- Status changed from new to closed
OK, it looks like all is well now.
Note: See
TracTickets for help on using
tickets.
The good news is that Sage compiles without modification. Of note
are bugs in Sage (passing -1 to something expecting an unsigned integer now always raises an error)
