Yes, this is most likely caused by a bug in the timeout mechanism. Rx
is keeping a timer (using setitimer/getitimer), and that timer is for
some reason reset. This should normally not happen, since the timer is
set to a timeout of about a year/several years.

My suspicion is that, somewhere, there is a call to setitimer after
the first one (with a lower value), but I cannot find such a call. I'm
currently working on this issue.
