If you are using linux, have in mind that the memory is often not 
returned to the OS even after a (libc) free. If you check with tools 
like `top`, it'll still show as assigned to the process.

What I had to do (both in D and in C/C++) was to call malloc_trim [1] 
manually to have the memory actually sent back to the OS.
