return TestResult in numexpr.test()

What steps will reproduce the problem?
1. Run python -c "import numexpr; numexpr.test()"
2. If a test fails, there's text output but no return value
3.

What is the expected output? What do you see instead?
It would be nice to see a return value.
Being able to do something like this is useful: 'python -c "import numexpr,sys; 
numexpr.test().wasSuccessful() or sys.exit(1)"

What version of the product are you using? On what operating system?
2.1

Please provide any additional information below.
In test_numexpr.test, changing 
unittest.TextTestRunner().run(suite())
to
return unittest.TextTestRunner().run(suite())
will accomplish this.
