remote shell weirdness? (zsh-2.6beta)

[Yoshiaki KASAHARA <kasahara@xxxxxxxxxxxxxxxxxxx>]

Dear Zsh developers,

When I replaced my zsh from 2.5 to 2.6beta (now beta13), I found that 'xon'
stopped working correctly.  When I xon to a host which uses zsh-2.5,
xon silently exits and the specified client is individually runs (no
extra process remains)....this is the supposed function of 'xon'.
With 2.6beta, xon won't exit until the client is terminated, and some
extra process (xon itself & rsh) also remains.

Try the following sentence:

rsh -n host 'sh -c '"'DISPLAY=local:0.0"' '"xterm </dev/null >/dev/null 2>&1 &'"

I believe if your login shell on the 'host' is zsh-2.6beta, it won't
finish until the xterm is terminated.  It seems that non-interactive
zsh will wait termination of the *background* child process.....Is it
a feature or a bug ?

I'm not a subscriber of this list, so please send me a carbon copy of
replys (if any).

Thank you.
