Wrong coverage report with `--boxed`

[Peque]

Note: Not sure if this is a pytest-xdist or pytest-cov issue. I can close this and reopen it in pytest-cov if needed.

Having the following test_asdf.py:

import pytest


def square(x):
    return x ** 2


@pytest.fixture(scope='function')
def dummy_yield(request):
    yield 2
    print('Fixture tear down...')


def test_square(dummy_yield):
    assert square(dummy_yield) == 4

Running:

pytest -n 1 -xsv --cov

Results in 100% coverage, as expected.

Running:

pytest -n 1 -xsv --cov --boxed

Results in 88% with line 11 (the tear-down print() statement) not being covered (or not reported as covered).
