system("zsh") fires up a child zsh just fine. But when
the zsh exits, the Perl process is suspended!
Repeat by:
prompt$ perl
print "one: "; <STDIN>;
system "zsh";
print "two: "; <STDIN>;
^D
one: foo <<<=== I typed "foo"
subprompt$ date <<<=== this is the subshell
Sat Feb 19 09:39:19 PST 2005
subprompt$ exit
two: zsh: suspended (tty input) perl
prompt$ fg <<<=== note we came back to outer shell prompt!
[1] + continued perl
bar <<<=== note the print worked, wasn't hung until read
prompt$
Is it a problem with zsh, or system(), or some complex interaction?

Probably zsh; I don't see that. Does the same thing happen for you from
a shell script? What does setopt show?

I can't reproduce this with zsh 4.2.0 on Mandrake 10.1 (perl v5.8.5
built for i386-linux-thread-multi) or zsh 3.1.9 on Solaris 8 (perl
v5.8.6 built for sun4-solaris).

I can reproduce it on macosx with bleadperl and zsh --version eq
"zsh 4.1.1 (powerpc-apple-darwin7.0)".

Ahh, didn't know the platform would be the problem.
Yes, this is OSX.

This was an old bug (zsh forgot to reset the original tty foreground
process group after having created its own process group), it is fixed
in current CVS and I believe in 4.2.0.
