[Serusers] CPL proxy timeout

[Bogdan-Andrei IANCU]

Terry,

I was considering adding variable timer support in CPL once the tm /ser 
implementation of variable timers gets to a better version - I have some 
performance reserve regarding the current one. Also I could just add 
this feature and let the admin to decide to use it or not ;-)
