Thanks. However, just as in my original message in the other thread,
I'm wondering if there's a solution that doesn't require a separate
executable. In other words, is it possible to get a subshell's pid in a
zsh-only manner, without using anything like the "stat" executable nor
the "getpid" utility described above?
Thanks.
