What I don't understand is that if the problem is due to the precmd
call from TRAPCLD, then why do I get

ypig:~[1]>                                                    <12:15:32
[1]  + done       sleep 5
ypig:~[1]>                                                    <12:15:35

and not

ypig:~[1]>                                                    <12:15:32
[1]  + done       sleep 5
ypig:~[0]>                                                    <12:15:35

and why do I get "ypig:~[0]>" only after a window resize *and*
typing [Enter]. If I do not resize the window, the prompt is not
changed.
