title: Git SVN was working, rebase now hangs
body: <p>I just did a <code>git svn rebase</code> no problem on Friday afternoon.</p>
  
  <p>Monday morning, it's hanging and resulting in an error like "WFSO timed out" </p>
  
  <pre><code>$ git svn rebase
  C:\Program Files (x86)\Git\bin\perl.exe: *** WFSO timed out
  C:\Program Files (x86)\Git\bin\perl.exe: *** WFSO timed out
  C:\Program Files (x86)\Git\bin\perl.exe: *** WFSO timed out
  C:\Program Files (x86)\Git\bin\perl.exe: *** WFSO timed out
  C:\Program Files (x86)\Git\bin\perl.exe: *** WFSO timed out
  C:\Program Files (x86)\Git\bin\perl.exe: *** WFSO timed out
  Unable to determine upstream SVN information from working tree history
  </code></pre>
  
  <p>How do I get it back to working again? 
  Last time it got into this state, I did a <code>git svn fetch</code> all over again, which worked, but rebuild the local repo from scratch and so was very time consuming.  Hoping there's a better way.</p>
