I have no new ideas to investigate at present. The problem is that the
cygwin algorithm in dll_init.cc is able to force windows to use a higher
relocation address, but cannot force it to relocate lower than the one
it finds by default. I was hoping that by always loading from low
address to high then we could side-step this problem, and indeed in many
cases this does work. But sometimes windows relocates to a higher
address than it did in the parent, and we are just not able to correct
this.

If anyone knows where I can find a specification of the windows
relocation algorithm, then maybe I can find a mechanism to implement
true fork() semantics, or prove once and for all that it just cannot be
done. Until then, or some other flash of inspiration, I will be working
on some of the other (many) outstanding issues with my gnome port.
