Ummm, assuming that "reauth" is going to run for a long time, I would guess
that the problem is that stdin/stdout/stderr is still tied up by reauth, and
that rshd is waiting for those descriptors to close.
The fact that pagsh is in a defunct state is really a red herring in this
case. It's going defunct because it's exited, but rshd doesn't clean up
the status until it gets a close.
What you probably want to do is something like this:
rsh foo my_script "<" /dev/null ">&" /dev/null
Or in your script:
#!/usr/afsws/bin/pagsh
exec < /dev/null > /dev/null 2>&1
[...]
