[New-bugs-announce] [issue16441] range usage in gzip module leads to excessive memory usage.

[Chris Withers]

New submission from Chris Withers:

gzip.py uses range instead of xrange in two places.
This results in excessive memory usage when opening large .gz files.
I actually bumped into this using tarfile.

Am I right in thinking that range basically *is* xrange in 3.x? If so, this bug applies only to 2.6 and 2.7.
