Most of the Windows test failures are due to the path separator not being "/". The general approach I took here was to keep paths in "URL form" (ie using "/" separators) as much as possible, and only convert to native paths when we attempt to open a file. This will allow the most consistency between different host OS. For example, data structures that store paths still store them with "/" delimiters. Functions that accepted paths as input and return them as outputs still use "/".
