Calling FFC just-in-time (JIT) compiler, this may take some time.

Anyone else experience this?
from dolfin import *

V_h = FunctionSpace(mesh, "DG", 1)
v = TestFunction(V_h)
L = assemble(v*dx)
print "L = ", L
Me, me, me! :)

This is fixed now.
Hurray!

It was an intricate caching problem relating to
reuse of the dummy form v*dx that FFC creates when JIT compiling
elements (for use in DOLFIN FunctionSpace).
I fixed it by making sure FormData is not cached when compiling
elements but a proper solution (removal of the FFC dummy form) should
be implemented instead. I've added a FIXME in jit.py.
