> Currently, the {{MountTableResolver}} caches the resolutions for the {{PathLocation}}.
However, this cache can grow with no limits if there are a lot of unique paths. Some of these
cached resolutions might not be used at all.
> The {{MountTableResolver}} should clean the {{locationCache}} periodically.
