To help alleviate rocky chat server reboots, WhoList messages will be
withheld in the first 15 seconds from server start.
When a lot of chatters were online during a reboot (e.g. 50 or more),
they would all try and reconnect after 5 seconds and each login was
broadcasting Who List updates to everybody else logged in. With the
surge of logins in a short time, these WhoList messages would fill up
the buffers of each recipient, kicking them offline for being too slow
to keep up with messages; only for that recipient to reconnect again.
The average user may have experienced 2 or 3 disconnects when the chat
server reboots.
To help alleviate the spam of messages being sent out:
* Presence messages are withheld for the first 30 seconds ("has joined
the room" notifications)
* Now, WhoList messages are withheld for the first 15 seconds.
After 16 seconds of uptime, the server will send a WhoList to everybody
currently online to catch them up.
To accommodate this, the front-end will show a spinner and say "Waiting
for Who List..." when the page is connected but no WhoList has been
received yet. Under normal operation, this spinner won't be visible
beyond a brief moment as a WhoList is normally sent upon joining the
chat.
