I think we're getting a little off track here. I don't think anyone is
talking about doing anything that requires code modification.

The OP merely asked how long must he wait between posting a message and
deleting a user from the list to be sure the user still gets the post.

I still think that once the "completed" message for the post is in the
Mailman smtp log, changes to the subscriber list for non-digest
subscribers won't affect who ultimately receives the post. The
message-id of the post is in the log, so you can tell if the log entry
is for the post in question if that is an issue.

Further, you could just look at the range of completion times in the
log and pick say double the maximum that you see as a "reasonably
safe" time to wait.
