PR Summary

In an effort to reduce the number of exceptions we throw as standard flowcontrol, this PR adds

bool TryCreateFileStream(
    string path,
    string streamName, 
    FileMode mode, 
    FileAccess access, 
    FileShare share,  
   out FileStream stream) 

as a non-throwing alternative to CreateFileStream.

This makes the code slightly faster and debugging slightly less annoying.
