Ah, that sounds like QNX. Linux rt seems to be much superior. See

http://rtlinux.cs.nmt.edu/~rtlinux/ with archives at
http://rtlinux.cs.nmt.edu/cgi-bin/wilma/rtl#browse .

The reference to QNX was that the SIMPL project was intending to use the
same primitives. I don't know whether there are any real semantics: parts of
it look CSP-ish, but in my quick skim I didn't find the word "event" which
isn't promising.
