Uhm... I think we have a problem here.  I really don't think I have the
most complete 32 bit installation, far from it, but I already have 1121
DLLs with addresses down to 0x37a00000.

If Windows willy-nilly rebases DLLs with start addresses < 0x38000000,
and if rebase starts to disable addresses below 0x38000000, we're in a
bit of a fix...
