> 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.
