Chris Tate 3d00b5b837 Size encoded messages to their nodes and wake a channel's owner once per batch
A message encoder started its node array at 16 nodes of 184 bytes and
kept the array, with its unused capacity, until the message was
received. A port that queued many messages held about 3 KB of zeroed
memory per message: 200,000 queued numbers took about 590 MB, and the
page faults made postMessage cost about 1.3 µs. The node array now
starts at 4 nodes and is trimmed to the message's node count when
encoding ends.

scr_channel_post posted a wake event, and with it a pipe write and a
condition broadcast, to the receiving thread's mailbox for every
message. The owner's loop counts a port with queued messages as ready,
so only a message that finds the queue empty needs to wake it.

bench/channel-messages, added here, posts 200,000 messages (numbers and
small objects) on a MessageChannel before the port delivers any.
