[issue29533] urllib2 works slowly with proxy on windows

Serhiy Storchaka added the comment: This is how Python works. This can't be changed without changing the compiler, the format of .pyc files (for saving warnings) and importing system. And this may slow down normal compilation due to generating warnings for saving them in .pyc files. I don't th
