I don't really see a any serious problem this would cause.

However, creating a thread per port does seem
somewhat arbitrary, and would mean wasting (a small amount of) resources
apparently for no gain if there are lots of HCA ports in a box.

Further, renicing the mad thread to work around bug 229
<https://bugs.openfabrics.org/show_bug.cgi?id=229>
is easier if there's a fixed number of threads:
as it is, the threads come and go on hotplug,
so the renicing must be repeated on each hotplug event.
