 i tend to calculate a process' memory consumption in deltas, meaning,
 how memory it consumes in addition to the shared sections. So i
 usually take a look at the write-able
 and private consumption as reported by pmap. ( pmap pid ).
 Please note, there are numerous discussions of how to estimate
 system/process memory consumption. Consider for example an in-kernel
 inode, it is not counted in the process address space even though it
 serves the process, what about in-flight bio, skbuff ?
 
 
 These problem are very common in the embedded world, we  fear of being
 oomed :)

In addition, I also check free memory before running the app, after
starting, several times, etc.
