I'm not sure it makes sense to integrate this in pytest-services?

xvfbwrapper master (not yet on PyPI) supports file locking for getting displays and using it is as simple as:

@pytest.fixture(scope='session')
def xvfb_display(request):
    with Xvfb(width=1280, height=1024) as vdisplay:
        yield vdisplay

It works fine for xdist runs too.

makes total sense to me
