Also, it's currently very slow on large structures, being implemented in
Erlang (using gb_trees and debugging BIFs like erts_debug:same/2). Do
not use in production if the structures may be huge.
The erts_debug:flat_size/1 function is fast and implemented in C, but
doesn't give you the true size since it ignores sharing. If Kostis
Sagonas' work on sharing-preserving copying operations was included in
OTP, we could have an efficient version of erts_debug:size/1.
