Title: Update fastcache to most recent version

The frequent timeouts in the slow tests have likely been due to the timeout signal getting lost in fastcache: pbrady/fastcache#26. The latest release addresses this issue with better error checking. The `No output for 10 minutes` errors during the slow tests should become significantly less frequent.
