There are several notions of "real time" here. One is hard real-time
deadline-driven scheduling. Is that what's actually in SVR4? (I
somehow doubt it!)
The other is "soft" real-time, as described by the "real-time"
scheduling extensions is POSIX.1b(?). This could be implemented
relatively easily in NetBSD, and indeed i've made a start at setting
things up so that I could be implemented, but haven't had time to get
all of the changes integrated yet.
