This module is based on the vaultfuse.py module and will eventually
become the new vaultfuse.py module once integration and refactoring
of the existing vaultswift.py is complete.
Currently this module is temporary for the 2.6 release and will be merged
into a new vaultfuse.py for the next release.

rx } ztj| W Y dd}~X nX dS dS )aÆ Utility to check the tmpfs cache and return stat() from that.
This method looks to see if the object (directory) exists in the
local cache and will perform a stat() locally instead of calling
all the way to the backend.
Args:
object_cache_path (str): Cache path to the object we need stat infor on.
Returns:
Dictionary of stat() information or None if object does not exist.
