> Multi-token filesystem support and its interactions with the MR
> {{TokenCache}} is problematic. The {{TokenCache}} tries to assume it has the
> knowledge to know if the tokens for a filesystem are available, which it
> can't possibly know for multi-token filesystems. Filtered filesystems are
> also problematic, such as har on viewfs. When mergeFs is implemented, it too
> will become a problem with the current implementation. Currently
> {{FileSystem}} will leak tokens even when some tokens are already present.
> The decision for token acquisition, and which tokens, should be pushed all
> the way down into the {{FileSystem}} level. The {{TokenCache}} should be
> ignorant and simply request tokens from each {{FileSystem}}.
