Forked process, I hope :)

No, it doesn't.  Loading a library is purly process lokal on Windows.
Cygwin DLLs(*) have special startup code which allows to register them
in the process and to re-load them in the child process at fork time.

(*) Actually, any DLL using this special entry point would work.
    Native Windows DLLs just don't, usually :}
