 Another nvme-killer job seems to be building either lang/llvm or
 lang/rust from pkgsrc, with MAKE_JOBS=12.  Setting MAKE_JOBS_SAFE=no
 for these packages allows them to run to completion.
 
 This is on a not-too-old machine, with decent (but no longer great)
 CPU and _lots_ of RAM:
 
 ...
 [     1.000000] total memory = 127 GB
 [     1.000000] avail memory = 123 GB
 ...
 
 # cpuctl identify 0
 cpu0: highest basic info 00000014
 cpu0: highest extended info 80000008
 cpu0: "Intel(R) Core(TM) i7-6900K CPU @ 3.20GHz"
 cpu0: Intel Xeon E[57] v4 (Broadwell), Core i7-69xx Extreme (686-class), 3200.46 MHz
 ...
 
 (Yes, it takes a long to create and save a crash dump...!)
