Actually, it might be but I don't really know.  The specific problem
manifests during fork.  Since fork overwrites the heap, you can't
rely on mallocing anything until after fork returns.

In the case of dynamic loading we probably are ok but since this has
bitten me once, I'm assuming that with a small tweak here or there
it could bite us again and then we'd be scratching our heads over
this again in a few months.
