#define LESS_THAN_OR_EQUAL_PID (  a, b   )     ( (a)->pid <= (b)->pid )

#define MEMINFO_FILE   "/proc/meminfo"

Method:. At start, create a sorted list of all pids, these become the 'up' list. Check for any mem or cpu events Regex match the 'up' list, remember those that matched and their 'command' in a 'watch' list. Each poll interval: get an update of the sorted group of all pids, call it 'new up' list compute the set difference of a='up' and b='new up' pid in a && in b -> still up, call this the 'old pid' list pid in a && ! in b -> was up, now down, call this the 'dead pid' list pid ! in a && in b -> new up, call this the 'new pid' list loop thru 'dead pid' list, for every pid in 'watch' list, generate an event, use stored 'command', remove from watch list regex match the 'new pid' list, generate events if regex matches, add to 'watch' list set 'up' to be 'new up' free list elements in 'old pid' and 'dead pid'
