title: Invoking python under CygWin on Windows hangs
body: <p>Installing a new Windows system, I've installed CygWin and 64
  bit Python (2.7.3) in their default locations (<code>c:\cygwin</code> and
  <code>c:\Python27\python</code>), and added both the CygWin bin and the
  Python directory to my path (in the user variable PATH).  From
  the normal command window, Python starts up perfectly, but when
  I invoke it from <code>bash</code> in the CygWin environment, it hangs,
  never giving my the input prompt.</p>
  
  <p>I've done this on other machines, previously, but always with
  older versions of Python (32 bits) and CygWin, and with Python
  in a decidely non-standard location.  Has anyone else had this
  problem, or could someone tell me what it might be due to? </p>
