This is not going to work, period.  When you copy a DLL to the working
directory it will be that DLL that is used instead of the previously
loaded DLL.  It is the way the DLL search order works.  You'll see
failures and perhaps even lock up your OS.  Try this with the CYGWIN
DLL and you'll not be able to ls or rm.
