So I should only need the heartbeat on that client's setup as well,
right? Getting rid of extra heart beats would be nice.

It seems to be running, but I've run into a problem with bconsole. Once
I started the job, if I run bconsole and then "status dir", the console
hangs. If I strace the bconsole process it's stuck in a select call.
>strace -p 18452
Process 18452 attached - interrupt to quit
select(4, [3], NULL, NULL, {9, 461287}) = 0 (Timeout)
read(3, 0x655d80, 5)                    = -1 EAGAIN (Resource
temporarily unavailable)
select(4, [3], NULL, NULL, {10, 0})     = 0 (Timeout)
read(3, 0x655d80, 5)                    = -1 EAGAIN (Resource
temporarily unavailable)
select(4, [3], NULL, NULL, {10, 0}
