PS1, Line 540:     waitInitialResetCompletion(dbName);
I can use some feedback for this problem. Alternative fixes are:
- Drop this waitInitialResetCompletion().
- Change all internal callsites to getDb() to obtain writeLock instead of 
readLock.

Option 1 will cause slight inconsistency during startup / initial reset.
Option 2 may reduce concurrency by obtaining stricter writeLock.

Thus, I go with this getDbNoWait() approach.
