 after running with this fix:
 
    http://mail-index.netbsd.org/source-changes/2021/06/27/msg130457.html
 
 for a few days, i am convinced of two things:
 
 - this was the main cause of leaking that i was seeing.
 
 - unfortunately, it's clearly not the only one.
 
 
 the leak rate is far less than previously (5-10x less), and the
 consumed by "kmem-00192" increases if eg, i run make eg, xterm
 very active, so i'm reasonably sure it's still leaking, but after
 over 4 days, there are only 13k allocated pages (previously, it
 would be at least 100k.)
 
 this is not yet fully confirmed, i need to install a dtrace 
 enabled world and dtrace it.
