Going in a different direction: I set up 118 GiBytes of
swap (so: RAM+SWAP=150 GiBytes).

It made little difference, things apparently being
killed. (No OOM messages showed up.)

top ended up showing:

last pid:  5160;  load averages:   0.44,   0.37,   0.32 MaxObs:   0.57,   0.40,
  0.33                                                                         
                up 0+00:15:40  23:53:52
894 threads:   10 running, 863 sleeping, 21 waiting, 113 MaxObsRunning
CPU:  0.0% user,  0.0% nice,  3.1% system,  0.8% interrupt, 96.1% idle
Mem: 4364Ki Active, 679936B Inact, 19356Ki Laundry, 31114Mi Wired, 28145Ki Buf,
176428Ki Free
ARC: 28784Mi Total, 1041Mi MFU, 27687Mi MRU, 54317Ki Header, 3547Ki Other
     27955Mi Compressed, 28154Mi Uncompressed, 1.01:1 Ratio
Swap: 120831Mi Total, 130232Ki Used, 120704Mi Free, 4324Ki In, 32268Ki Out

(I adjusted the number formatting used.)

So enabling SWAP space looks to not be a way to avoid the MRU/Wired
related issue.
