processes' smaps files (/proc/PID/smaps) give delitaled view into the
internals of the kernel, on the address space and memory region mappings.
If you check your smaps file for a process, you can see which arena belongs to
which library, including stack and heap usage (which mappings "doesn't have
library" those also belong to heap).
You can classify the memory into more arenas it's depends on your decision,
just watch the libraries name.
You can do it with Gtk also, all you need is to have a kernel after 2.6.14
with smaps support. I should you to check Linux::Smaps perl module and if
you'll use it, the procedure will be quite easy.
