I think that the tuple is not the problem here, it's the
fact that so many objects are recorded in the memo to
later rebuild recursive structures.
Now, I believe that recursive structures in pickles are
not very common, so the memo is mostly useless in these
Perhaps pickle could grow an option to assume that a
data structure is non-recursive ?! In that case, no
data would be written to the memo (or only the id()
mapped to 1 to double-check).
