It supports messages too. So what? The topic is shared memory
programs that are going to run on this DIPC DSM platform unmodified.
In order for your point to be meaningful, there had better a large
class of multithreaded applications which use Sys5 semaphores as their
synchronization mechanism.
So perhaps you'd like to show the long list of multithreaded applications
which use Sys5 semaphores? And while you are doing that, you might
also show the somewhat longer list that use Solaris or Posix semaphores
and mutex's. And then you can explain to the unwashed masses how the
Sys5 stuff does a system call while the Posix stuff uses shared memory
with atomic operations and is several orders of magnitude faster than
the Sys5 stuff.
I'll be happy to put down my megaphone down when you start guiding
people in a sensible direction. You are leading unsuspecting people
down a path that many of tried before and has been repeatedly shown to
be nothing but a waste of time.
