Not really an issue, more a reminder for myself...
Update test VMs with current releases of python 2.7, 3.4, 3.5 and 3.6
Run test suite on OSX 10.5, 10.6, ..., 10.13
(i386, x86_64, ppc)
Fix issues found
Find a way to automate running tests on multiple OSX versions
(basically a script that starts a number of VMs in order and runs the testing script in them, collecting the results)
