Hello,
+
+In fact, we don't want to know the theorical limit. we know that we can
+change this value in the kernel sources and recompile it.
+
+What we don't know is the thread number limit after what the system uses too
+much CPU. In the linuxthread faq, they
+said that an application should not create more than 100 thread. In this
+case, we have to forget the solution where each
+socket is on a thread and use a blocked receive(). The problem is that
+select() is quite slow and if we have only 100 thread,
+each thread needs to manage, with a select(), around 50 players and we ll
+lost lot of time to create the array for the select()
+and check who have wakeup the select().
