The zip module does not have a close method, and so calling unzip leaves the file in an open/locked state. Fix is here:
Landed in kriskowal/master kriskowal/refactor. I cherry-picked; you're tracking cadorn's stuff, right? Does it work for you?
I have pulled in cadorn's master, and unzip still works with it. Or are you saying that cadorn's master should fix unzip to close? I don't see anything in cadorn's zip.js that would close.
No, unrelated; tusk does not work for me on cadorn/experimental and was wondering if anyone else had succeeded in using it. So it would seem; I'll have to look deeper.
