My comment was mostly just to point out that it's only a partial fix and 
it will eventually fail with an OOME once the deflated size is too big 
for the BAOS. I don't have a strong opinion on whether the complete fix 
is done in one, two or many PRs but I think the first step could be to 
use the "useTempFile" path when the entry size is larger than some (10s 
of MB?) threshold.
