Title: Check socket descriptor limit. #153

When calling select(), there's an upper limit for the socket descriptor
which is defined as FD_SETSIZE. When the socket descriptor is higher
than FD_SETSIZE, a call to select() will not work as expected, at least
for the proper sockets.

This patch adds an error message and an assert as well.
