> since users may be doing multiple file operations at the same time, a single task in
fuse, can never call close() on a filesystem (ie libhdfs::hdfsDisconnect) because there may
be another thread for the same user.
> as such, either fuse-dfs needs to do reference counting or FileSystem.Cache needs to
or maybe enable a mode where one can turn off the Cache??
> I currently am not seeing any problems in production, but I am still running 0.18 version
which keeps only one connection as root.
