The fact that these pesky command line arguments do differ may be an
*ahem* argument to wrap up this functionality in an FPC library function
so the user does not need to remember/fiddle with/update his code for
the various differences and the code will run on e.g. OSX, Linux,
Solaris, AIX without modifications.

... and if, for some reason, ps functionality is implemented in another
way (e.g. no ps but /proc filesystem is available), obviously this
library function could be extended...

Of course, this all depends on reliable OS detection etc, which, looking
at earlier discussions here and going from experience, is not that easy
