If there's no way to detect the correct units directly then falling back
on an OS check would work.

Stephane did do some work on refactoring limits code that never got
fully finished and merged a couple of years ago.

It does appear to always be zero. The ksh93 ulimit that acts as /bin/sh
on Solaris 11 prints:
  max memory size (Kibytes)      (-m)  not supported

There's no -m option at all for the ulimit on Solaris 10.
