This seems to be a repeatedly reported problem, but not one which anyone
who is capable of patching has been able to reproduce.  One idea is to
check whether you have some rogue driver (antivirus or webcam tend to be
culprits) that interferes with cygwin in such a way that it triggers these
defunct processes, and disabling the driver might clean things up.

Try '/bin/kill -f' to use Windows process killing instead of cygwin (yes,
you are right that cygwin can't kill a cygwin process if it has locked up
in a defunct state).
