Source: python-plac
Version: 1.3.4-1
Severity: serious

Dear maintainer,

python-plac will randomly fail to build because the testsuite performs
timing/benchmarking. This will vary on (for example) CPU and I/O load.

  ____________________________________ test3 _____________________________________
  
      def test3():
          t0 = time.time()
          plac.runp([gen(9), gen(9)])
  >       assert int(time.time() - t0) == 1 # it must take 1 second, not 2
  E       assert 2 == 1
  E         +2
  E         -1
  
  /build/1st/python-plac-1.3.4/.pybuild/cpython3_3.9_plac/build/doc/test_runp.py:26: AssertionError
  =========================== short test summary info ============================
  FAILED doc/test_runp.py::test3 - assert 2 == 1
  ========================= 1 failed, 28 passed in 6.12s =========================
