      Description

      oam/oamcpp/oamcache.cpp has a global mutex that can slow down execution b/c of lock contention, namely boost::mutex cacheLock.
      The existing implementation of OAMCache can also re-read configuration file holding the lock from either disk or OS buffercache in certain conditions. I also remove this functionality to reduce the lock contention.
