Since we don't have *at() syscalls readily available to us,
lei-daemon may call ->poke_dst in the wrong relative directory.
Despite not having *at() syscalls, we can still capture the
"$MAILDIR/cur" directory handle at pre_augment time so we can
reliably call futimes(2) on it using the `utime' perlop.
