If you think there is a bug could you explain how to reproduce it?

@echolumj I can't begin to review this PR until I have clear description of the problem that it's intended to address, it could well be that you have just misread the intent of the code and this PR might be introducing a bug rather than fixing one.

[robertosfield]

I have been reviewing the code and believe your PR is correct, but incomplete as we shouldn't be adding entries when the availableCount is zero. I'll merge this PR and the add the required check, thought this check for zero perhaps should be elsewhere with the entry in the map removed completely.

I have added an extra check and inline comments to better explain what is going on:
