Well, in my case things eventually get back to normal.  The "kill -HUP" 
I was running just sat there for about 10 or 12 minutes before telling 
me that the PID didn't exist.  When dump(8) has the problem, it slows 
down to an absolute crawl (a 20GB partition takes 10 to 14 hours to 
run).  Funny thing is it seems to probably affect only a single file 
system, since I can still start new xterms and do "other stuff".  Like 
when dump is stalled, I can still read my home directory - just not any 
thing on the fs being dumped.

I've been seeing it since around 4.99.45.
