a ReadWriteLock) must be used to ensure that a message, its
ancestors, and descendants are not accessed by any other threads
while the message is being modified. Field reads, getter methods,
toByteArray(...), writeTo(...), getCachedSize(), and
getSerializedSize() are all considered read-only operations.
