The following first 3 commands are OK. The 4th one hangs zsh,
with Ctrl-C and Ctrl-\ having no effect. This happens whether
MULTIOS is set or not.
zira% echo >&- > >(cat -n)
1
zira% echo >&2 > >(cat -n)
1
zira% /bin/echo >&3 > >(cat -n)
zsh: 3: bad file descriptor
zira% echo >&3 > >(cat -n)
zsh: 3: bad file descriptor
