The latest issue of OpenLine (from NCR E&M Columbia) has a two page article
on NCR's implementation plans for multi-processor unix.  Rather than retype
the whole thing I'll summarize the major points (IMHO):

1.  Will be based on SVR4   (SVR4 MP)
2.  USL (AT&T) will release SVR4 MP in 2nd quarter of '91.
3.  NCR wants to be one of the first with commercial release of SVR4 MP.
4.  Will be fully symetrical.
5.  Kernel will be multi-threaded.

In a sidebar, the article states that applications developed in SVR4 'will
run unchanged' on SVR4 MP, providing that the developers write portable
code, meaning using standard system calls.  

Question:  Does that mean that there will NOT be a common ABI between
SVR4 and SVR4 MP, so that programs will have to be recompiled?
