Patch to allow more granular aborting.

[Theo Schlossnagle]

I'm confused now.  In a previous mail, you suggested I use the builtin
libgmp mechanism to replace the allocators.  It appears libgmp indeed
has replaceable allocators, but then when it goes to allocate they are
not used. I results in I me being unable to wrap realloc and throw and
exception on NULL return.

At that point, I'm only left with the replaceable abort that I
proposed originally -- which is quite surgical.
