Relocations of standard "statically loaded" dlls can fail on fork the
same way that dynamically loaded dlls do. Windows doesn't guarantee
that the base address will be the same in the "forker" and "forkee" and
it seems like something in the forked process throws off windows so that
it chooses a different location for some dlls.
