a scintillating post just ducks in under the wire, and can appear after I lock a thread. I lock it, refresh my screens, and voila! someone has posted after the lock, or so it appears. What actually happened is that someone clicked the submit button a fraction of a second before I applied the lock.
In the case of a deletion your post would simply be ignored by the server, and would be trashed, never to astonish our readers with its insight and elegant turn of phrase.
