I'm about to give up and go home for the weekend.  Here is where rlogin is
stuck in the child process:

#16 0x61049408 in fhandler_socket::wait (this=0x616e50a4, event=0x6e8)
    at ../../../../cygwin/winsup/cygwin/fhandler_socket.cc:723
#17 0x61049b92 in fhandler_socket::recvmsg (this=0x616e50a4, msg=0x22eb10,
    flags=0, tot=8192) at ../../../../cygwin/winsup/cygwin/fhandler.h:365
#18 0x6104963f in fhandler_socket::readv (this=0x616e50a4, iov=0x22ebc0,
---Type <return> to continue, or q <return> to quit---
    iovcnt=1, tot=8192)
    at ../../../../cygwin/winsup/cygwin/fhandler_socket.cc:800
#19 0x6109fc2e in readv (fd=3, iov=0x22ebc0, iovcnt=1)
    at ../../../../cygwin/winsup/cygwin/cygheap.h:303
#20 0x6109f95c in read (fd=3, ptr=0x404070, len=8192)
    at ../../../../cygwin/winsup/cygwin/syscalls.cc:369

just one stupid question...  I'm probably way off base, but it looks like
the WSAEnumNetworkEvents call on line 726 of fhandler_socket.cc might
return events for the parent process's copy of the socket as well as the
child's in a forked process.  Could that be an issue?

I'm just grasping at straws that I don't understand and trying to be
helpful at the same time :-).
