You have to be a bit careful about what "immediately after reading" means. Actually, I think it means "immediately after the file handle indicates it has reached end of file".

Interesting. This would explain my observations. But if the file handle is not closed immediately, this Conduit is not much better than lazy readFile, is it?

I have a simpler reproducer for this below.

Yes, this is a nice minimal demonstration of the problem.

However, there is sadly not a large ecosystem around Bluefin, and no Zip library.

My program would also require a Tar library.
