I wanted something rather light weight, and open sourced of course.
So I settled on RTMK (Johan Rydberg), since it seems to address both.
See http://rtmk.sourceforge.net.  Its not actively being developed
(stopped in 2002), version 0.2, but if you don't provoke it with
bad API calls, it doesn't panic ;-)  I now have 3 modules up and
running in Ada, and this includes name service, console and IDE
driver (the console driver is still largely C). I also spent
considerable time building a binding to rtmk, which is strongly
typed.

Naw, I did the quick and dirty thing. The problem of course is that
the GNAT RTL must not go looking for POSIX services
that aren't there. So there were a few C API calls, that
I had to divert, or otherwise neutre ;-)

I don't have tasking or protected types, but I seem to have most
of everything else to work with. This is a refreshing change from
pragma No_Run_Time!!!
