What is the stack trace? At what point in PacketSender are we trying to
send the messages, or is it from somewhere else?
Here's a snippet from a stack trace I got after adding the exception to
the Logger call:

Check the stack trace. WouldBlockException is thrown when a peer is so
backlogged that we can't allocate a new packet number. So we requeue the
messages we need to send, since we have pulled them off the queue in
order to send them, and we can't send them yet.=
OK, it seems I did understand what's going on and apparently there's not
bigger cause than the peer is backlogged, so it looks like I didn't miss
anything (which is good).
What do you think of the waiting between queued message send retry
attempts idea?

Perhaps we should wait a little bit before trying to resend queued
messages? Perhaps the wait time should be proportional to the number of
messages queued, up to some threshold (maybe keepalive send frequency)?
According to the source:
public void requeueMessageItems(MessageItem[] messages, int offset,
int length, boolean dontLog) {
// Will usually indicate serious problems
What could cause this? Failure to get acks from a peer for awhile?
