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.
