That is about a big as we have tried. As soon as you scale up some
things start hitting you, some functions actually start taking way too
much time (the client freezes for a long time when there are many
hoarded files)

When the file is closed, venus stats the container file to figure out
the new size. At that point it detects the fact that the cache has
overflowed. It makes sure the stuff gets to the server, and then throws
the file out of the cache. After this venus refuses to fetch the big
file back, because there is not enough space in the cache.
