Sebastian: Does this remove a cache that is not in use by the program (since it now looks by looping over the static mCaches)?  Such behavior is not specified explicitly in the API but I think it would be useful to be able to remove a cache without having to first open it.

I imagine this would also not fix the case where a file was deleted from under an open mmap, such as by a different process calling removeCache().  One way or the other we will have to handle SIGBUS, which is something I will try to work on.
