All of the tests relying on ps are going to fail on OS X and probably BSD as well
since there is no "--no-headers" option on ps unless it's the GNU ps utility.

Actually looks like it's the -o option that's failing: 

[user@host]$ ps -o rgroup
ps: rgroup: keyword not found
ps: no valid keywords

the man page for ps on OS X indicates there is no "rgroup" keyword (actually there
does not appear to be a group name keyword, only group id "rgid" for some reason). We
will probably have to convert the group id to a groupname in order to test process
groupname. 

The test_process_vsz_memory I'm not sure about, it looks like some other kind of
issue since the ps command is completing but the numbers aren't even close.

Splitting the vsz test out to a separate issue #73 since it appears the unit test is
doing what it's supposed to there. Leaving this open to address the groupname problem
on OS X.

Marking as won't fix since ps just doesn't supply a groupname anywhere on OS X and we
already check the rgid in the posix tests anyway.

Status: WontFix
