With the changes to -current as of NetBSD 9.99.48 Sun Mar  1 17:38:46
EST 2020, the complete lockups I was seeing when the 4G of phymem
was exhausted as well as the other issues seems to have been somewhat
resolved.

The largest improvements were last week when the big uvm changes
were checked in but I haven't seen a lockup since the last couple
of changes made on Sat or Sun. Those appear to have finally made
this system stable enough to use again, though there still appear
to be memory alloc/dealloc and swap issues because I have to reboot
at least once a day when phymem is exhausted and the system becomes
unusable due to severe swapping. This is when basically nothing is
still running and disc cache is only taking up a tiny bit of phymem
and only a tiny bit of swap appears to be in use.
