my issue is this: prlimit -t5 echo foo works fine (cpu limit) but
prlimit -s5 echo foo (stack size limit)
prlimit -v5000 echo foo (address space limit)
both return: prlimit: failed to execute echo: Argument list too long
My system is linuxmint version 19, prlimit -V returns 'from util-linux 2.31.1'
