title: Eclipse/PyDev: Sync System PYTHONPATH runs continuously
body: <p>When Eclipse/PyDev is open I see an operation running in the background, over and over (as if stuck in an infinite loop), in the lower right status area telling me "Sync System PYTHONPATH (100%)".  I have a single Python interpreter configured, everything runs fine, but I wonder if this continual update of the PYTHONPATH is something to be concerned about.  Maybe there's something amiss which is triggering this sync operation to occur every second or so?</p>
  
  <p>Eclipse:
  Version: Luna Service Release 1 (4.4.1)
  Build id: 20140925-1800
  PyDev:
  Version: 3.9.0.201411111611</p>
  
  <p>OS: Windows 7 64-bit</p>
  
  <p>Thanks in advance for any suggestions!</p>
