Pollsets for Win32

    exception Too_many_descriptors

    val pollset : unit -> Netsys_pollset.pollset

This is a pollset implementation that works for

- sockets, and
- named pipes as provided by `Netsys_win32` (add the descriptors returned by `pipe_descr` or `pipe_server_descr` to the pollset)

The number of descriptors that can be added to the pollset has a quite low limit (usually 63 sockets or 31 pipes). If the number is exceeded the exception `Too_many_descriptors` is raised (by `add`).

POLLERR, POLLHUP, and POLLNVAL are not detected by this impl.

    val threaded_pollset : unit -> Netsys_pollset.pollset

This implementation overcomes the limit on the number of descriptors one can add to the set. It is, however, only available for multi-threaded programs, because it uses helper threads.
