Right.  Unless I wanted to provide a wrapper for LoadLibrary (which I
don't) this will always be the case.

The problem is that, for some reason, Windows loads DLLs in different
spots in the "parent" and "child" when you do a "fork".  It has every
right to do this, of course, but it screws up fork.

I went to considerable effort to work around this last year by
instituting an ugly hack in the fork code which worked around this.
My main motivation for getting this working was perl since I am a
very long time perl user.
