   But, at the risk of sounding like a broken record...  Do
   we have benchmarks showing that RTL gc is one of
   the major causes of slow compile speed?
   
It's not the GC it's the resulting data access patterns
that result, and such overhead won't show up in normal profiling since
such overhead is simply spread all over the compiler.

That's the purpose of hobbling together a "hack" implementation
of refcounting, to get some performance comparisons.  You don't have
to do a "final" perfect implementation to realize a tree usable enough
for simple initial benchmarking.  Based upon those results, we can
decide to continue or not.

But hey if people are going to be silly enough to require
pre-benchmarking before even laying a finger on the refcounting
bits, no problem we'll just have to wait for me to work on it
then ;-)
