theres a kernel file cache for cached mounts (see the -C option),
tho its broken in labs plan9.
pages of executables are cached.
the disk fileservers implement a buffer cache to avoid going to disk
and do lazy writing out dirty filesystem blocks.
plan9 is a distributed system. the disk fileservers are really
network fileservers. and the local kernel isnt the only
mutator so it cant invalidate the cache without going to
the fileserver.
