I'm repeating myself, but: what's your point? 'id' exists on Linux,
and the script fails (in the worst possible way, ie, might remove
inappropriate shmem segments) on all other platforms if it's unable
to detect the correct EffectiveUser. I would argue that checking for a
numeric, nonzero EffectiveUser is going to make it safer not less so.
