I am a Cygwin beginner too, so if this is not useful
to your discussion just ignore this message:

In my limited experience the PID and the WINPID are 
always (?) the same for Cygwin processess INITIALLY.

After a HUP signal (kill -s HUP pid, my Cygwin process
(if it survives) will have the SAME PID but a new WinPID.

I use this fact to assure myself that I have succeeded
in the HUP to get Exim and other programs to reload their
configuration.
