 When I found signal 9 errors on NetBSD 10.0 BETA with an evbarm
 installation, I had not noticed console messages (they were not shown
 in /var/log/messages) about swap. I transcribe them here:
 
 [ 22555.40164641 UVM: pid 19688 (t_exhaust), uid 0 killed: out of suap
 [ 53830.57815951 UVM: pid 17972 (t_exhaust), uid 1000 killed: out of swap
 [ x656x.93092051 UVM: pid 24498 (t_exhaust), uid 1000 killed: out of suap
 [ 85716.67184551 UVM: pid 28714 (t_exhaust), uid 1000 killed: out of swap
 
 The install has no swap defined:
 
 $ swapctl -q
 swapctl: no swap or dump devices in /etc/fstab
 
 I added a swap file and the test succeeded, once. On a second try,
 though, the test failed again.

 I will run more tests.
