...and your listserver sent it to me now at 13:47 2/28/99, about 36 hours
later and after I had already received several replies and made several
replies to the replies and gotten several replies to *those* ... !

What the heck's wrong with it? It should be a FIFO queue, right? And it
certainly shouldn't send a list message to Eli nearly immediately and then
wait about a whole DAY to then send me my copy!

Even if there are billions of subscribers and after getting a message it
does take a whopping 24+ hours to go from A to Z sending copies to all of
these subscribers, my last name begins with a D, and his begins with a Z...
