Well, suspending the whole function also causes undetermined behavior
in case it is intended to modify the shell environment.

I think there are two possibilities that avoid such a problem:
1. Suspend the whole shell.
2. Ignore the TSTP signal (temporarily or completely).

Possibly, when receiving a TSTP signal, if interactive, zsh could
give the choice between several behaviors.
