I'm not familiar enough with workqueues. How well does it deal with
frequent calls (under heavy network load I guess this can be called
very often). What happens when the thread blocks, does this defer other,
unrelated workqueues ?
Also there is (from worqueue_enqueue(9)):
"The enqueued work will be processed in a thread context.  A work must not
 be enqueued again until the callback is called by the workqueue(9) frame-
so it's not as easy as a persistent thread and cv_broadcast() ...
