How about keeping u.in(V) in C++ and then map it to something suitable
in Python so that one may write

  if u in V:
      ...

in Python. Does anyone know how to do that?

Not necessarily one Function for each thread, but it should be
possible to extend Function to keep one cell etc for each thread.
The variables are accessed by functions cell(), facet() so it should
be possible to hide it.
