Splendid.  So, if we increase the high watermark, can we increase it
to a power of 2, to make best use of allocated memory (which is
doubled at each reallocation)?  Or is it possible that some other code
in term enqueues character even if the queue is suspended (for
whatever reason)?

The second question would be, if we increase the high watermark, it
seems to make sense to also increase the low watermark, to improve
flow control.  Any advice for this?
