That depends, I'd say. Using a stable API to get the information means
future versions of the program will most likely never ever break.
check_proc is one of those programs that has gotten broken several times
over the years because the ps output changes slightly, or someone changes
a parsing routine that's used by too many architectures.

Not really. If you can get check_proc to work with pstat_getproc()
I believe that would be a better way to go. Ofcourse, the plugin devs
may well disagree with me.
