New description:
We should introduce `check_` variants of the Sage memory functions which
`raise MemoryError` upon failure.
I also propose to add a BSD-inspired [http://www.openbsd.org/cgi-
bin/man.cgi/OpenBSD-current/man3/calloc.3?query=reallocarray&arch=i386
sage_reallocarray()] function.
Attached branch introduces the functions and uses them in a few places as
proof of concept.
