 one of the systems i see the problem on is currently running
 a pkg build of over 1000 packages, and usually will see this
 problem.  this is an arm64 16-core machine with 64GB ram and
 a single 1T nvme.  ie, everything is just "/" for me.  is there
 a way to modify this script usefully for me?  i'm not sure how
 much will be written to any fs :)
 
 thanks.
