title: Repeated single or multiple tests with Nose
body: <p>Similar to <a href="https://stackoverflow.com/questions/4088354/is-it-possible-to-use-nose-to-run-one-test-multiple-times-concurrently">this question</a>, I'd like to have Nose run a test (or all tests) <code>n</code> times -- but <em>not</em> in parallel.  </p>
  
  <p>I have a few hundred tests in a project; some are some simple unit tests.  Others are integration tests w/ some degree of concurrency.  Frequently when debugging tests I want to "hit" a test harder; a bash loop works, but makes for a lot of cluttered output -- no more nice single "." for each passing test.  Having the ability to beat on the selected tests for some number of trials seems like a natural thing to ask Nose to do, but I haven't found it anywhere in the docs.</p>
  
  <p>What's the simplest way to get Nose to do this (other than a bash loop)?</p>
