change int to unsigned (just make it uniform,
part of it was already unsigned)
change path by pointer to path by value
since it will be copied on write; fixes bug
where path changes from underneath measure
Allow empty paths to still initialize measure state.
This fixes the GM failure from the earlier check-in attempt
in CL 113269.
