Doesn't that give a potentially bad effect, that any lib-gnome-goop
library allocations that happen before that point will get done by
gnome's custom allocator, but it will subsequently get freed by the
system allocator?  Sounds like the express train to Segfault City Central.

Even if that doesn't fail .. wouldn't we wind up with a bunch of allocs
(prior to this point) that Memcheck doesn't know about, and a bunch
that it does?  That don't sound good.
