title: How to fix "address space is already occupied" error on fetch/commit?
body: <p>Started recently, basically every time I try to fetch or commit it gives me this weird error. It'll continuously try to "refetch/recommit" until I give up and <kbd>Ctrl</kbd><kbd>C</kbd>.</p>
  
  <pre><code>C:\cygwin\home\git\new_trunk&gt;git sf
        1 [main] perl 760 child_info_fork::abort: address space needed by 'cygreadline7.dll' (0x960000) is already occupied
  
  C:\cygwin\home\git\new_trunk&gt;git svn dcommit
        1 [main] perl 2672 child_info_fork::abort: address space needed by 'cygreadline7.dll' (0x980000) is already occupied
  </code></pre>
  
  <p>Any idea why this is happening?</p>
