Description

Recently (#1943), function CPLReadLine() has been found as very slow on Windows. This problem may be related to the logic at cpl_conv.cpp:365

The solution should not break the CPLReadLine() support for text mode files.

This issue is also related to the #1989

Milestone: 1.5.01.5.1

Putting off to 1.5.1. Change(s) to CPLReadLine/CPLReadLineL must be made very very carefully and we have limited time left to do extensive testing.

Pursue this as time permits, not release critical.

Is this still true: "function CPLReadLine() has been found as very slow on Windows"

Is there a way to test this slowliness with some ready GDAL utilities? Some measures would be needed as well for judging what is slow and what not.
