@vlovich Thank you for your PR contribution.
I read the issue you filed and agree with your reasoning on the solution. I think you're missing a parts.pop() call, see my comment in my review.
Give it a test and let me know. I haven't touched npm in years but I can probably publish a release for this bugfix after it's merged.

Sorry for the delayed reply. I hadn't seen this. Good catch. I left the pop in there locally but somehow corrupted the patch when applying.
Gracefully handle multiple threads deleting an object at the same time. When two concurrent requests come in to delete the last two remaining objects in a given path, they'll be racing each other trying to delete and cause a spurious deletion failure for one of them. Fixes jamhall#788
