That assumes that the IMAP server notifies instantly, instead of polling
internally at a fixed interval.  This, in turn, assumes some form of
message passing between the MDA and the IMAP server.

I find it remarkable that anyone can get bent out of shape because it may
take as much as a minute or two to be notified about a newly arrived
email; particularly as it may have taken some ungodly amount of time for
the message to have travelled from the senders MSA and the recipient's
MDA.

We have a perfectly good facility called instant messaging for real-time
communication.
