Comment:
I think it is best to follow your suggestion and split stuff.
Soon (perhaps tomorrow) I'll return to the old patch, i.e. without
touching the groupoid stuff. In a to-be-created ticket, I'll try the idea
for caching groupoids that avoids memory leaks but uses ''strong''
references, as explained in my previous post.
However, I think the weak references to the underlying set of actions is
an integral part of #715 - without it, the memory leak would not be fixed
at all; so, I'd not split #715.
