- * Win32 select() will only work with sockets, so we roll our own
- * implementation here.
- * - If you supply only sockets, this simply passes through to winsock select().
- * - If you supply file handles, there is no way to distinguish between
- *   ready for read/write or OOB, so any set in which the handle is found will
- *   be marked as ready.
- * - If you supply a mixture of handles and sockets, the system will interleave
- *   calls between select() and WaitForMultipleObjects(). The time slicing may
- *   cause this function call to take up to 100 ms longer than you specified.
- * - Pipes are not checked for writability or errors (errno = ENOSYS)
