So much for useful problem reports.  I tried it with a rsh/rlogin server
on a RHEL4 machine and I could reproduce the hang.  It turned out that
it has nothing to do with rsh, but with rlogin.  It has nothing to do
with Cygwin from CVS, but it also happens with the current 1.5.24 and
older releases.  It has nothing to do with Vista, it also happens on
other Windows versions.

The problem is a race condition in rlogin when setting the tty mode to
!ECHO/!ICANON which for some reason only occurs in the standard Windows
console in notty mode.  I've uploaded a new version of inetutils which
hopefully fixes this problem.
