add stack usage - currently no
May be useful in determining a) if a crash is caused by stack overrun or b) if a program is using a lot of stack (and just happens to have a TRACE/TLOG in the right place).
This is mainly interesting just because it was thought to have minimal impact.
It's one of those things that if it were there, it may end up showing something.
With address randomization and ru_isrss currently "unmaintained" it does not seem that
this is currently feasible.
Just keep in mind -- one day, it may be easy.
