Comment(by SimonKing):
I have slightly modifies [attachment:trac11521_triple_homset.patch]: In
the old version, I had created a `TripleDict(50)`, but meanwhile I learnt
that the parameter of the `TripleDict` should not be even and should best
be a prime number. In the new version, it is prime...
Concerning the weak references: Why exactly is the experimental patch so
slow? Is it because the access to the weakly referenced actions is so
slow? Or is it because the actions are garbage collected even if their
domain/codomain is still alive, so that the actions are uselessly created
over and over again? I suspect it is the latter.
