Fail more softly if we can't execute "ps"

Browse source 
Summary: If, e.g., $PATH is broken we may not be able to run "ps". We'll explode pretty hard, currently. Instead, just show a harsher warning.

Test Plan: Changed "ps auxwww" to "psq", which doesn't exist on my system. Loaded page, got warning instead of explosion.
