There's probably nothing in clientSet, so it is waiting for
nothing.... you almost always want to have just one call to
select in the program, not two, the whole point is to combine
checks.
I wrote a thing you might want to read too:

How do we wait for an ‘or’ of multiple asynchronous events in
this kind of code? In WinNT iirc there is a very nice o/s
function that can wait on various kinds of asynch i/o, waiting on
operations of different types if I’ve understood it correctly.
The kind of thing I might want to do is wait on an or of IP
packets arriving, send-completion of IP packets, timers
completing, IPC messages coming in, key presses or event mouse
events and the order in which these events arrive is of course
not predictable. I might want a key press event to break out of
something or to control an application. Everyone wants timer
events for timeouts.
