Message: SERVER-4328 fix slownightly/background.js
Message: SERVER-4328 more reporting in serverStatus of the lock times for each individual db lock
Message: SERVER-4328 continued work on lock reporting stats. take out mess i made mpreviously
Message: SERVER-4328 - db and global lock and acquisition time for read and write
Message: SERVER-4328 refactor stats a bit and make mongostat db locking friendly
for db locks, mongostat will show the db with the highest lock % and what db it is
I think that last commit needs more polish - we should update the help text in stat.cpp, and also the columns no longer line up from line to line in mongostat since the variable length dbname appears in the middle of the line.
