} It should print `INT' but it doesn't.

That's because zsh has been extremely clever and has `exec'd "sleep 60",
so there's no zsh process around any more to execute the trap.

Try:	Src/zsh -fc 'trap "echo INT" INT; sleep 60; sleep 1'

and you'll see ...

Perhaps zsh's tests for whether the last command can be `exec'd should
include testing whether there are any user-defined traps in effect?
