Comment(by SimonKing):
Some old code is ''not'' using the cache: There was some coerce map
created in sage/rings/residue_field.pyx, whose parent was not created by
`Hom(domain,codomain)`, but directly by `RingHomset(domain,codomain)`.
Changing it fixed at least one segfault. I wish all segfaults would go
away so easily...
