Package caching does not work on windows due to device not being implemented in py2 on Windows

[instinct-vfx]

Package caching is by default configured to not allow caching on the same device. The check for "same device" does not work on windows though and always results in a false positive.

There are multiple possible ways to fix this:

• Add version and platform checking to said function checking for the device. python < 3.4 and windows being problematic. Not sure how to deal with this though as this would make the setting be ignored completely.
• Add version and platform checking to the default config (similar to coloring). That would be rather transparent?

Oppinions?

given this is deprecated py2 only, and that checking py version in config would require more work, I think simply ignoring the device in this case would suffice. Even if pkg caching occurred on the same device, it would hardy be a big issue.
