Well, my guess is this had to do with cov-core being installed in the 
root conda rather than a conda environment.
I've uninstalled and manually deleted the file; the problem is I have a 
feeling that I manually deleted that file before and it came back :-S

Still no idea why site.py is looking at 
/Users/chris/.local/lib/python2.7/site-packages/ in what's supposed to 
be an isolated environment...

...and of course, now I can't reproduce this one locally. I wonder 
what's different to cause coverage to care whether or not picky is 
imported when run remotely versus locally?
