And here I was waiting for the dust to settle. My thoughts:

- the general idea of a cache directory is good
- tests should be fixed in the same patch that introduces the changes
for bisectability
- running check-code is strongly encouraged
- running the test suite is also encouraged (and check-code is run by
the test suite so it's easy to spot when you haven't done it!)
- you've got the right idea about ordering patches so that optional bits
are at the end
- I have mixed feelings about introducing another opener object, as this
is moving us into fairly fine semantic distinctions (compare opener vs
sopener and opener vs copener)

So let's see a fixed up patch 1+2 and we'll consider patch 3 after that.
