      Description

      In looking at stack traces of a NN under a heavy block allocation load (around a thousand per second) I see that a lot of time is being taken up in stringification of log messages for addStoredBlock. This code can be optimized to use a single StringBuilder instead of a lot of nested toString() calls.

        I don't have any good benchmark on this, but the attached code uses a single StringBuilder, so should be faster.
