I don't think that in and of itself that's a good enough argument.
I'd wait until we actually encouter such a beast.

Yes, this would be a good idea.  But, it should still be moved in
separate pieces!  The generic parts of the collector could be moved to
libiberty.  So could valloc.  But, I still don't feel they should be
combined.
