Thanks I've checked code as sow interesting solutions, maybe I'll ask some more
questions about desicions.


As I see all servers uses accept-forkIO i.e. one green-thread to accept sockets
and then runs another thread for each connection, in this thread function from
ServerOptions is run, that function read Socket/Handle itself.
Also I've seen another way of implemeting server 
[http://sequence.complete.org/node/258]
in this solution author also uses accept-forkIO style to create workers, but
main thread is used for all socket IO, i.e. accepting, reading and writing data
back, this server uses STM channels to send data between threads, as I see this
is orthogonal way of dealing with server. I'm interested if there is some more
ways that are more affectfull in some cases that accept-forkIO(socketIO) or
accept(socketIO)-forkIO.
