Real-timeness of System V R4?

[Mark McWiggins]

My company does quite a bit of work in factory and warehouse automation,
where a certain degree of real-time control is necessary in controlling
warehouse machinery, etc.   We've mostly been running DOS for these 
parts of the application; since there's very little operating system
there, there's very little to get in the way of the application.  Of
course, that cuts both ways; there's also no memory protection, no tasking,
etc., etc.

We're always looking for something better and are aware of various Unixish
efforts in the real-time direction (LynxOS, etc.).   I've seen various
mentions of System V R4, besides finally coming in with the nice 
Berkeleyisms, being more configurable towards real-time applications.

I haven't seen any details on this.  Is there someone close to the porting
effort that could comment?  Is SysVR4 going to be a true contender in
this arena?  We don't require microsecond response time, but it is nice
to stop those machines before they drive through walls, etc ... :-)

Thanks in advance for any insight.
