profiling improvements

• Would be nice for memory profiling to also record the free memory on each node. This determines when swapping is about to start. E.g.

grep 'MemFree' /proc/meminfo

Just added parsing for MemFree into memInfo. As well as normal profiling, I wonder if it'd be useful as a function-object style (emit warning when things are getting tight).

I've been mulling some other ideas about function-objects, but doesn't quite fit here (discuss by telephone).

perhaps some runTimeControl ?

• fv solvers do not grow memory (- lagrangian might)
• mesh generators are generally the problem and these do not use runTime++ (but do use profiling)
• so any trigger should be added to the profiling instead?

changed title from profiling does not show free memory on node to profiling improvements

changed the description
