it would seem like using `bufio.Scan()` is very slow for heavy concurrent I/O, ie. when r.Body is slow , instead use a proper binary exchange format, to marshal and unmarshal the LockArgs datastructure in a cleaner way. this PR increases performance of the locking sub-system for tiny repeated read lock requests on same object. ``` BenchmarkLockArgs BenchmarkLockArgs-4 6417609 185.7 ns/op 56 B/op 2 allocs/op BenchmarkLockArgsOld BenchmarkLockArgsOld-4 1187368 1015 ns/op 4096 B/op 1 allocs/op ```
