> select() is fine except for two problems:
Select also wastes memory. An fd_set is usually implemented as including an
array of FD_SETSIZE entries. Therefore, if FD_SETSIZE is 1024, even if I'm
only using select() to deal with a single socket, it's still allocating
enough memory to hold 1024. Poll solves this by using a dynamically allocated
storage.
