Some care must be taken. At the end of your .cshrc:

if ($?prompt && ! $?TCSH) then
  if ("$prompt" != "" && -X zsh) then
    setenv SHELL `which \zsh`
    if ($?loginsh) set SHELL = "$SHELL -l"
    exec shexec $SHELL
  endif
endif

where shexec is the attached Perl script. The tcsh exec bug has been
fixed in recent versions of tcsh; so, you may not necessarily need
shexec.

Perl POSIX module not found! The non-standard file descriptors attached
to a tty (as those let open by this buggy tcsh) could not be closed.
