 I upgraded two other current systems yesterday. Both have wm(4) interfaces
 and act as gateways (one is 1:1 and the other is 1:N). Neither one showed
 any signs of this PR with stock -current, so no patch was requierd.
 
 I checked 'ident /netbsd' for these systems, and for some reason the
 problem system had several source files with revisions older than
 the working systems (although the sources were synced approximately at the 
 same time; though for the patched system I needed to sync later from 
 another mirror, as anoncvs.us2 was giving corrupted/partial data at the 
 time). I've now synced the problem system sources again, and upgraded 
 to stock -current without any patches. Panic on shutdown is gone, and can 
 not be re-produced.
 
 I can only assume that the problem I experienced was caused by anoncvs
 related problem(s), and only by chance looked like what is described
 in this PR. Your quick patch fixed it for me, which in turn gave me 
 confidence in upgrading the other systems, and then realizing it
 may not have been a real problem, after all.
 
 As I only experienced this on one current system, and even in there only 
 briefly, I can not say whether this is (or even has ever been) a 
 problem in -current. I don't run releases on our systems.
 
 Here are some details from the interfaces I have, and where -current
 is working properly (= this PR is not an issue):

 I'd be happy to test any wm-related patches against current, if there is
 any need, though I realize this PR seems to concern releases.
 
 
 Thanks again for looking into this,
