} I've noticed that under certain conditions, shell functions called from

Whatever this is dates back a long time.  In zsh-3, the sample script
doesn't appear to call the exit trap at all via "main" or "exit0"
though it does if "exit" is called directly.  In zsh-4 the behavior
is the same as in current zsh-5.
