So it is indeed not possible to obtain global status anymore? But how 
would one check global heap usage then? The necessity to collect such 
information by iterating through all threads somehow scares me... In 
particular, if some thread happens to hang or dies unexpectedly. Still, 
is there some recommended way to estimate heap usage per application, at 
least approximately?

Ok, I'll try to figure.

Thank you!
