> utils.pm::run_command does not consistently return the correct exit status.  
> It often returns -1.  This looks to be due to timing of when REAPER is 
> called.  Sometimes REAPER enters its 'while waitpid' block, sometimes it 
> doesn't.  Either way, the exit status is inconsistent.
> I don't know of a benefit of entering REAPER for children of vcld child 
> processes.  It can be bypassed by adding the following in run_command after 
> the process is forked:
> $SIG{CHLD} = undef;
> If this is added, the exit status is always correct.  It is also correct if 
> the entire subroutine is changed to call the command via backticks.
