title: httplib CannotSendRequest error in WSGI
body: <p>I've used two different python oauth libraries with Django to authenticate with twitter.  The setup is on apache with WSGI.  When I restart the server everything works great for about 10 minutes and then the httplib seems to lock up (see the following error).</p>
  
  <p>I'm running only 1 process and 1 thread of WSGI but that seems to make no difference. </p>
  
  <p>I cannot figure out why it's locking up and giving this CannotSendRequest error.  I've spent a lot of hours on this frustrating problem.  Any hints/suggestions of what it could be would be greatly appreciated.</p>
