Subject: [PATCH] nproc test

I wondered why vsyscall_reverse_next-32 takes in CI kind of long.
And suspect this has something to do with JULIA_CPU_THREADS=128
at a CPU supporting 64 threads?

model name	: AMD EPYC 7502 32-Core Processor
nproc shows also 128
lscpu: failed to determine number of CPUs: /sys/devices/system/cpu/possible: No such file or directory
