Profiling memory can be tricky because the operating system may not
return memory *immediately* as requested, and it might mislead you in
some situations. So do not trust too much in memory profilers to be too
exact and rather focus on the big picture (i.e. my app is reclaiming a
lot of memory for a large amount o time? if yes, then start worrying,
but not before).
