After reading some material, it seems that a timer (for Ajax) is necessary
to pool the server for messages.

With java or C/C++, there is no timer, ie a client just listens on a socket,
and it is notified once data is in. Correct me if I am wrong (ie the client
does not pool the server in this case).
