Read it and weep:

I've no idea what we're supposed to do here. We're using removeDirectoryRecursive having written the tarball. So the files opened to construct the tarball have been completely read and hence closed. So we should not have any of the files open so the recursive remove should not fail.

Discovering why it does actually fail will need someone with a Windows debugger and some patience.

Does this happen repeatably? Is it the same file every time? Does it happen with all packages or just this one?

Still need more info. Tempted to close this, but keeping it around for now.
