I'm debugging the adaptive machinery and I'm seeing some strange
behaviour.

Take a look at the following simple test code:

  from dolfin import *

  mesh = UnitSquare(2, 2)
  V = FunctionSpace(mesh, "CG", 1)

  print
  v = Function(V)

  print
  v.function_space()

  print
  v.function_space()

I would expect that the FunctionSpace constructor is called only once.

But it seems to be called three times. Once at the top as expected and
then every time function_space() is called:

Debug: creating function space [at
dolfin/function/FunctionSpace.cpp:42 in FunctionSpace()]
this = 0x335e190
registering V = 0x335e190

Debug: creating function [at dolfin/function/Function.cpp:49 in
Function()]
V = 0x335e190
registering v = 0x33622d0 for V = 0x335e218

Debug: creating function space [at
dolfin/function/FunctionSpace.cpp:64 in FunctionSpace()]
this = 0x336c420
registering V = 0x336c420

Debug: creating function space [at
dolfin/function/FunctionSpace.cpp:64 in FunctionSpace()]
this = 0x336c420
registering V = 0x336c420

Is this expected? Note that the constructor is called three times but
the pointer (this) is the same in the two last calls.
