It doesn't have to be that way if this is causing problems.  Maybe it
would make sense to store these things in the cygheap now since I think
the allocation-next-to-the-dll predates the cygheap.  If that isn't
appropriate then we could also just store the information in some
easily-relocatable block and copy that block to forked processes.
