The UNIX implementation of the jobserver requires UNIX-style pipes and
POSIX-style signal handling, including sigaction(), the concept of
non-blocking reads, etc. To the best of my knowledge, not all of these
things exist on Windows.
Also to the best of my knowledge, no one is working on a Windows
implementation using whatever Windows-specific technology might be
appropriate for this type of situation (I have no idea what that might
be).
If someone is interested in thinking about it, or engineering a
solution, I'd be happy to discuss it and think about the best way to
integrate it into the current implementation. I can provide some detail
as to how exactly the UNIX version works for reference, and I have a few
messages Rob Tulloh sent me back when we were doing the UNIX
implementation discussing Windows-related issues I can forward to anyone
who cares to look into this.
