I think it is more powerful to have one check_procs that can run any
number of filters.

So you can have checks like 'warn if more than one of Joe Dbadmin procs
has a vsz exceeding a limit'

Or whatever combination suits the needs of the install.

Actually, in implementing all the checks al a series of filters, it woul
be nice to be able to specify both AND and OR.

The check_vsz is just a special case in this framework.
