[issue9647] os.confstr() does not handle value changing length between calls

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I agree with Victor that two calls to confstr() should be enough. An example in confstr manpage uses two calls and I think there is no many software (if any) in the world which does more.
