That depends on how Windows maps DLLs.  I'm fearful that two
applications that both import from "cygwin1.dll" will share a dll,
even if the search path would result in different dlls being found.

If you're debugging a dll yet relying on a stock dll at the same time,
it's prudent to give them separate names.

What about the mount tables, though?  Depending on *what* you're
experimenting with, you may still need to isolate other parts of the
dll's shared resources.
