 We need to do documentation/usage changes with this. Also have you
tested what happens for code which uses the old cache defaults (I mostly
assumed we had this behaviour traditionally because the only alternative
was to fail with much less obvious permission denied errors anyway).

 The patch should also change all the repo_gen_decompress() calls
outside yumRepo. Also what about xml => sqlite conversion?

 It might even be worth having this behind some kind of config.
variable, although obvious that generates more code paths which sucks.
