The problem with select are well known. poll(2) removes the limitations of select(2) and improves speed and features. The problem is that poll(2) isn't available on all platforms. This means you need a poll(2)-emulation or create wrappers around other similar poll() functions. In libssh we use a poll(2)-emulation based on select for platforms which don't provide a poll(2) function like some Windows versions or UNIX systems. Windows Vista or newer version provide a poll(2) like function called WSAPoll(). To be able to support this call which is faster the the poll(2)-emulation and allows to use more…

kio_sftp updates
