I've heard that the problem may not go away with this fix also. Maybe
it is two problem?
Anyway: It is the queue for active transfers. The queue is only used
to requeue transfers that were active when an ubareset occurred. 
I have never seen an ubareset on a qbus-based machine, and very rarely 
on Unibus-based machines. (Only on a heavily-loaded ftp server).
