Subject: Change the behaviour of insp in windows to keep its window open, with
 some status text in the title bar. It also clears the screen now on startup,
 see the wrapper for what a nasty amount of code it is to do such a simple
 thing to a windows console :( Also, add somewhat of a hack to cut down on
 allocation time taken to map windows fd to a posix style fd in iocp engine.
