Thanks for changing the message, the update to ZipFile looks good to me
although I'm still surprised that the native tools support a CEN larger than
2Gb.
I'm slow to add myself as a Reviewer because I'm concerned about the test. I
ran it on a couple of systems and it take several minutes to create the ZIP
file. This test may potentially run concurrently with other I/O bound tests and
I'm concerned about intermittent timeouts. @LanceAndersen - do you have any
opinions on this?
