Igor Canadi	08be1803ee	Fix bad performance in debug mode ... Summary: See github issue 574: https://github.com/facebook/rocksdb/issues/574 Basically when we're running in DEBUG mode we're calling `usleep(0)` on every mutex lock. I bisected the issue to https://reviews.facebook.net/D36963. Instead of calling sleep(0), this diff just avoids calling SleepForMicroseconds() when delay is not set.
