In 3.6 importing antigravity prints a warning (although it does what it should do):

>>> import antigravity
/home/ivan/.../Lib/subprocess.py:761: ResourceWarning: subprocess 15501 is still running
  ResourceWarning, source=self)

This is probably related to http://bugs.python.org/issue27069

[brendan-donegan]

I think this is essentially a duplicate of http://bugs.python.org/issue27069, or at least fixing that will fix this (as the exception is caused by the webbrowser.open() call)

[ilevkivskyi]

It looks like this is fixed on master, but the problem still appears on 3.6

I have not seen this for quite some time so I'm closing this as fixed.
