I think I can answer my own question: jobs will fail to start. I set
LOWPORT=9600, HIGHPORT=9650 on my schedd machine and now I'm seeing:

2/9 19:11:41 (6.59) (3276): Sock::bindWithin - failed to bind any port
within (9600 ~ 9650)
2/9 19:11:41 (6.59) (3276): DCStartd::activateClaim: Failed to send
command ACTIVATE_CLAIM to the startd
2/9 19:11:41 (6.59) (3276): Job 6.59 is being evicted
2/9 19:11:41 (6.59) (3276): Sock::bindWithin - failed to bind any port

2/9 19:11:41 (6.59) (3276): RemoteResource::killStarter(): Could not
send command to startd
2/9 19:11:41 (6.59) (3276): logEvictEvent with unknown reason (108),

2/9 19:11:41 (6.59) (3276): Sock::bindWithin - failed to bind any port

2/9 19:11:41 (6.59) (3276): Can't connect to queue manager:
CEDAR:6001:Failed to connect to <137.57.142.135:9615>
2/9 19:11:41 (6.59) (3276): Failed to update job queue!
2/9 19:11:41 (6.59) (3276): **** condor_shadow (condor_SHADOW) EXITING
WITH STATUS 108

But it looks like the schedd is hanging on to a good 75% of the ports in
that range while running jobs are preempted for this machine:

Why won't the schedd give up a port for the shadow so it can start
running a job?
