I'm not an expert but I'm unimpressed with the way FreeBSD handles an
OOM situation on a desktop.

I have a FreeBSD desktop PC at home which is always under memory
pressure: Xfce, my Firefox, my wife's Firefox with lots of tabs, several
bhyve guests, a SMB server and other stuff. So the
"swap_pager_getswapspace(11): failed" situation is rather frequent. 

FreeBSD freezes, then kills some innocent random processes like
local_unbound, then it may slowly recover. Sometimes it guesses
correctly and kills the offender (firefox most often).
