And that's why it's important to find out how many applications
out there are still using it. From my personal perspective,
shm is not a good thing and it should be avoided.
It's the same story when P9 (or should I say 9P) broke the
long-standing promise of having a file around as long as
you don't close it. Turned out -- not that many apps failed.
Or so I was told, anyway.
Thanks,
