If python scripts are restricted from accessing zExceptions (for security 
reasons???) then why allow python scripts to trap zExceptions in bare 
try/excepts?  If the logic for not allowing zExceptions in plain vanilla 
python scripts is for security reasons, then allowing bare try/excepts would 
seem to be a security hole (though, I don't see the rationale for this).

My 2 cents.
