In r237513 on 6/23 I made a mistake that was corrected in r238124 on 7/5.
I can vaguely see a connection between kern.ipc.shm_use_phys and the
problem fixed in r238124.  So, I'd like to know if this problem still
exists.  Wait, however, until you see Kostik commit a change to
vm_pageout.c, before you update your system.


Here're the sysctls/tunables I have regarding shm:
