The problem on w32 is that w32 sends a message to the process when 
delete-process is used. W32 then expects the process to answer to some 
w32 message (can't remember which one right now). Cygwin does not answer 
to this message. Then w32 shows a dialog box and asks the user what to do.

IMO this is a bit inconvenient, but it could perhaps still be the best. 
But it works quite nicely AFICT with sending signals to Cygwin instead 
using interrupt-process or kill-process. So why not try these first and 
then shoot with delete-process if they do not work within a couple of 
seconds?
