This is a fundamental function for writing to a stream.
A block of arbitrary values with an arbitrary
tag is written into the
done argument should normally be
but may be used to build up a packet using a sequence
|writeStreamPacket calls, by setting
nil on all but the final call
in a sequence.
(Any write to the same stream by another job in the middle of this sequence will result in premature completion of the packet, which will emerge from the stream as two or more packets, with the interrupting foriegn packets interspersed.)
To facilitate writing the same packet to many streams, the arguments (other than the stream) are not popped.
If necessary, the job will block until space becomes available. See section |maybeWriteStreamPacket. See section |rootWriteStreamPacket.
