If the machine swaps or > something, we might get incorrect data with the sleep anyway.. Unfortunately the way plugins are done, post-ops are pretty much impossible to catch from the outside. And I really don't like this either. I would definitely prefer for the reply to the modifying client to wait until the memberof plugin is done, even if this means the operations will be slow. But I don't know if this can be done easily with the current DS architecture ... The problem is that we cannot even enter a read loop to wait smaller amounts of time until we get back the right answer because a competing client may change the membership while we are waiting and causing us to loop forever ...
