JIT failing to cache properly

[Prof Garth Wells]

Running py.test -k test_doc_string_compiled_expression_with_system_headers test_expression.py trigger complication every time it is run.

[Martin Sandve Alnæs]

Not a bug: the test checks that trying to compile an Expression with non-compilable code raises an exception.

[Prof Garth Wells]

There was a subsequent test, which to run the relied on this test running first. Is this test importing all of the UFC interface via Swig?

[Martin Sandve Alnæs]

I don't know but that's a separate issue from the description on top here.
