It would be nice to separate checking that files are in the cache when
they should be, and checking invariants that must be true.  Invariant
checking could be a slow background process that does a few ops and then
sleeps.

I have a similar usage pattern, but smaller.   I have about 350 MB in
my coda directory, and a 500 MB cache.  I keep all of it in cache via
walking the tree because hoard seems to be broken.  So I may not be
hitting the case you are.


I think the view is that what you are doing is reasonable and that if
coda the codebase doesn't cope now it's a bug.
