There are regularly two tests for vdirsyncer which fail when I build it
on my machine. I've resorted to running 'until guix build --no-grafts
vdirsyncer; do sleep 5; done', but this doesn't seem like a good
solution.

=================================== FAILURES ===================================
_________________________________ test_fuzzing _________________________________
tests/unit/test_metasync.py:129: in test_fuzzing
    a=metadata, b=metadata,
E   hypothesis.errors.FailedHealthCheck: Data generation is extremely slow: Only produced 4 valid examples in 1.01 seconds (1 invalid ones and 0 exceeded maximum size). Try decreasing size of the data you're generating (with e.g.max_size or max_leaves parameters).
E   See https://hypothesis.readthedocs.io/en/latest/healthchecks.html for more information about this. If you want to disable just this health check, add HealthCheck.too_slow to the suppress_health_check settings for this test.

Does anyone know how to work with hypothesis to fix this problem?
