after running with this fix:
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.
