need explicit?

Done.

This method should not reset usage.
Could you leave usage as is, or place NOTREACHED()?

[kinuko, 2012/05/11 06:59:34]

Done.

[tzik, 2012/05/10 08:31:00]

Maybe, we should check if the directory exists, and should return empty path if
!create && !exists.

[kinuko, 2012/05/11 06:59:34]

Done.
