cvs also doesn't like noisy scripts.

I take it you meant "tcsh -c /bin/true" (lowercase "c").  Your test above
only tests tcsh in non-login mode.  Try 'tcsh -l' or '(exec -l tcsh)' from
bash instead.

Both of these seem to indicate extra output from somewhere.

I'd say you have a noisy .login (or /etc/csh.login)...  If you rule that
out, we can look for other causes.

FWIW, simply "ssh user@host cvs server" should show you all of the output
your cvs client sees (and complains about)...
