[issue18003] lzma module very slow with line-oriented reading.

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

The patch is not so harmless. First, my change in BZ2File is not correct, because reading every line should be guarded with a lock (BZ2File is threading-safe). Second, for now all three compressing files are not only iterables, but iterators. iter(f) returns f, and changing this can have non-obvious effects. I think the patch is too complex for 3.5, we should have more time to analyze all consequences.
