[lldb-dev] Pipe issue on LLDB Windows?

[Zachary Turner]

This is a known issue.  But I don't think this is a regression.  It's just
always been this way.  Basically on Windows, select() only deals with
sockets.  It doesn't work with pipes, files, or anything else.  In other
words, ConnectionFileDescriptor is just fundamentally broken on Windows.  I
recently pushed a large refactor to the socket logic in
ConnectionFileDescriptor which is aimed at addressing this.  But it's only
one step of what I think will be a long process to get
ConnectionFileDescriptor working on Windows.
