[issue18515] zipfile._ZipDecryptor generates wasteful crc32 table on import

[Larry Hastings]

Larry Hastings added the comment:

Since this isn't a bugfix, it was inappropriate to check this in after feature-freeze for 3.4.  However it looks harmless enough, so I'm not asking you to revert it at this time.

I guess it's easier to get forgiveness than permission, huh.
