I was looking through the debug logs to try to figure out why my code is a bit slow for a simple task. I noticed that on every request that mongoid/moped is checking for who the master server is. Is this required for every request, and is it possible to cache what it thinks the master is? Also, it seems to be doing this twice for every server (notice the request times are different)

Here is the log: (3.0.0.rc)
