You should be able to do this without JavaScript by using streaming.

I'm interested in figuring out the memory peaks of specific code pieces. 
Even if memory gets freed up at some point, I'd still like to know the 
amount that was used just right before to be able to calculate the 
amount that would be used by concurrent processes.

And also to see the history of memory usage by methods compared to each 
other so that I know which part of the code I should rewrite to make it 
more memory efficient.

I use these tools and they work great. Only they've got nothing to do 
with memory consumption.

If I understand you correctly, you say I can only see the counted sum of 
these objects? But I reckon I still won't be able to calculate memory 
usage by this.

ruby-prof would have similar with its RubyProf::ALLOCATIONS I believe, 
unfortunately I can't get it to work. But anyway, your solution can be 
more than nothing. I'll check it out later on. Though I'm still keen to 
find a solution for what I described above.

Thanks.
