* fhandler_socket.cc (fhandler_socket::send_internal): Just use wmem size if 

the length exceeds it.
* net.cc (fdsock): Use 65535 as window size, just like the comment says or we
run into problems with DuplicateHandle.
* path.cc (patch_conv::check): Use set_path to set invalid filename.
* path.h (path_conv::path_conv): Ditto.
