Hello!

I was wondering if anyone has suggestions on the easiest way to 
time how long GC collections take? I haven't seen anything in the 
docs.

What I want is a clean non-intrusive way to log when a collection 
happened, how long my threads were stopped, how much total memory 
and how many blocks were recovered. i.e. how much garbage was 
created in between collections. Are there any hooks on the 
runtime?

Cheers,
-M

I thought there is a recently added compiler option that profiles 
the GC and creates a report now?

Should be included in 2.068 I think:

That's an allocation profiler, the other one mentioned by me reports GC
stats as requested by the OP.
