IMO, if you _need_ this, then you should be using Linux, not eCos.
The notion of processes and separate (or even protected) address
spaces are contrary to the basic [very simple] design of eCos.
That said, you could look at the work contributed by 3G Labs a
few years ago. It was very ARM specific though, and to make it
work on PowerPC would be an effort. See http://ecos.sourceware.org/contrib.html
for some details.
