Title: use a separate (memory-based) cache for sessions

This addresses issue #265.

Our sessions cache is using the same file-based cache that we use for page caching. This is "bad": file cache is slow, and if CACHE_TIME is set to zero, we will get different behavior for the session cache.

The change:
* Define a separate memory-based cache.
