> There is an optimization at org.apache.avro.generic.GenericDatumReader.getResolver, when
we cache creator thread and it's first returned value. At first, It looks redundant, because
it saves three calls to Map.get, which is unmeasurable, especially after Schema's hashcode
calculation optimization, made by the same author [~cutting], it's not obvious and adds additional
complexity. Also caching of current thread whould be a source of bugs in case of different
green threads libraries integration (which, actually, occurred during integration with Quasar).
