Title:
  document_ftp: stalled server at test4.yml

Status in OpenERP Addons (modules):
  Incomplete

Bug description:
  Affects 6.0 official series. Detected by buildbot v3

  We had seen the 'time out' kind of error in buildbot v2.5 . There, it
  was mostly caused by the fact that the ftp port is not configurable
  and parallel tests would conflict with each other. In the old
  buildbot, the 'document_ftp' module had been black-listed, so no tests
  ever ran against it.

  But, today, in buildbot v3, I saw this kind of error, which must be a _real_ bug:
  http://pefnos2.homelinux.org:8020/builders/OpenERP-buildbot-addons 6.0/builds/30/tests/document_ftp.test

  It only happens late in "test4", after hundreds of ftp operations that
  have succeded in test2, test3. And, if you examine builds 29, 28, 27
  ... , you will see that it happened at the same yaml command all the
  times. Weird.

  The 'time out' is our safeguard against such a server failure: we
  wouldn't expect any FTP command to take more than, well, 1-2 seconds
  anyway. Here, it takes 10. So, somewhere, the openerp-server stalls.

  I do suspect an unclosed db cursor (because ftp does some cursor
  management, in fact). It could still, however, be anything else.

  Although the document_ftp module is one of the black sheep, this bug
  could affect other parts of the openerp-server, so, please, take some
  time to investigate.
