added a 100ms sleep to the keep alive system to prevent it from having excessive cpu usage

The keepalive system should be 15sec, 15000ms

[Sweattypalms]

^ There is no point checking keepalive every 100ms. Since keepalive typically runs every 30 seconds, checking every 15 seconds ensures we catch all players' status even if they join right after a check, while still being far more efficient than checking every 100ms.
