Agree, the posted stats don't even indicate what is being measured,
and system-wide measurements are almost completely irrelevant to
something like this.  Free memory in particular on linux is
meaningless as it will ALWAYS go down over time as the cache is
utilized until it hits a level maintained by the kernel.  Free memory
should be relabeled "wasted memory" as in you paid for it but aren't
getting any value out of it.

What you really want to know is how much real memory the mythtv
process is actually using.
