I too have recently run across this problem. I have run the following
command under csh (SunOS and SCO) and zsh 2.3.1 (SunOS) for quite a
while (years) but it doesn't work under zsh 2.6-beta10 (SunOS):

    rsh -n host "env FOO=$BAR /bin/somecmd </dev/null >& /dev/null &"

Under csh and zsh 2.3.1 it returned immediately. Under zsh 2.6-beta10 it
doesn't return until the program exits (this was from SunOS 4.1.3 to
SunOS 4.1.3).
