Revision 539dd207df0283bbb218806cd317cd883ef21fff authored by Lei Jin on 14 April 2014, 16:34:59 UTC, committed by Lei Jin on 14 April 2014, 16:34:59 UTC
Summary:
Similar to GetImp(), use SuperVersion from thread local instead of acquriing mutex.
I don't expect this change will make a dent on NewIterator() performance
because the bottleneck seems to be on the rest part of the API

Test Plan:
make asan_check
will post perf numbers
