Design question

[Dragan Zubac]

Hello

1. You said Your design is to use single-process event-driven 
architecture. Could You just give some info about the design of backend 
workers or callback that are called when an event occur ? Do You use 
fork(),pthreads or something else to achieve concurency among things 
that are supposed to be done at 'the-same-time' ?

2. Is You software capable to handle 'long-lasting' TCP connections,for 
example far-end clients are supposed to connect to backend servers,they 
need to keep those TCP sockets open for a long time,and occasionally 
send/receive some data on those sockets ?

Sincerely

Dragan
