Subjectshared memory, mmap not recommended?

In a recent posting Linus Torvalds mentioned
( :

uses it anyway, but it would be more polite to just support it).

I was thinking about using mmap for shared mememory in my program, but now I
am reconsidering.
Is the System V or Posix mechanism for shared memory a better(it will be
supported in 2.4) choice?
