Well it's corrupt from the standpoint of setup.exe, which only knows
that it has encountered a file with the specified name but incorrect
size and/or MD5 based on the information in the setup.ini file.  Short
of AI there is no way for it to distinguish this case from the case of
something that is actually corrupt.

If people are uploading new packages (or otherwise modifying them once
"in flight") without bumping the version, then that needs to stop.
