If files are moved and the cache exists, it hangs up

[JJ]

If you change the structure of a cached folder and don't delete the cache. it will hang up.

To reproduce:

• Cache one directory foo with files bar baz
• mkdir foo/quux
• cd foo
• mv bar baz quux

Try to run the program again... It simply freezes.

What should be the behaviour? Why would a developer want to change the structure of the cached folder?

The idea behind 'freeze' is to allow for the documentation to be "compiled" and moved. But why would the folder structure need to be changed.

My paradigm is that messing with a cache except through the API is like messing with a modules code.

Well, he or she might want to do it because they've changed their opinion, as I did. it can simply happen. You might not want that to happen, but in that case it's better to raise an exception or a meaningful error instead of not doing anything.
