This patch provides an API from both Ruby and C to get two values:
  - ObjectSpace.live_objects: the count of live objects
  - ObjectSpace.allocated_objects: the count of objects allocated since the ruby interpreter started

This patch allows to profile memory allocation without changing the code too much.

See my comment on #19302. I have no wonder why it needs a 
year to get bugs fixed on anything but the core of the 
core: everybody wants matz to clear up before moving the 
little finger.

This is a very small, non intrusive patch. If you have 
doubts, then ask for clarification -- to me or matz. But 
don't expect me to fight for this patch. I'm already 
maintaining my patched Ruby and having one more in the 
queue will not change anything for me. I won't spend hours 
fighting for such small changes.

Was this discussed on ruby-core or elsewhere?

You have to convince matz and folks that this will be useful
for trunk first.

After noting that this allows Ruby profilers to keep track of
allocations per method call (and fast and well), I favor this
patch as it would add enhanced debug functionality "out
of the box" for all users.

what's the benefit over existing ObjectSpace func's?
