`run_command.sh` improvements

Lines 12 to 13 in ef44515

	local pid1=$1
	local pid2=$1

Should not there be $1 and $2?

I thought that as well a while ago, but after testing it, it seemed to not work the same (or, better), so I left it how it is.

A measurable improvement would be a welcome contribution!
