Is SYNC going to be a new kind of message? Is the SYNC response yet
another?
Either way, could this be used as a keep-alive for long-lived
connections? (some users of the current Smalltalk drivers report that
long lived connections over the Internet sometimes just die)
Also, with the new protocol, will the number of affected rows be
returned in a way that does not require parsing to fish it out?
