* Fix for mantis 0000040 After client logout remote host closed connection on Simulator makes sim unuseable->'Closed Connection Called'

Browse Source 
* I've fundamentally changed a few things, so this is experimental
* The routine that I used needs to be tested on Linux.  I don't expect it to cause a problem, but hey, it might.
* Child agents are still not logged off properly, so when the first set time out, the second set get logged off also, on the second log in if the second login is initiated before the first one fully times out.
