In the current release, long (>100K?) email messages cause zmailnotify
to spend a long time processing them (with the mailbox locked.) This
interferes with incoming mail. I'd suggest
1) changing "multiline" to detect a blank line (as end of
headers) and flush the rest of output, returning DONE
2) have "mbx_write" not use realloc, but create a large (10K?)
static array and just punt anything more than that (or at least not
realloc *so* inefficiently...)
3) on general principles, call pop_command("QUIT") and
pop_close() *before* calling mail_notify, so that the mailbox doesn't
stay locked while waiting for zephyr functions (at that, perhaps
z_kind should be UNSAFE, instead of UNACKED.)

ps. I'm looking at the sources in
/mit/zephyr/src/clients/zmailnotify/zmailnotify.c.
