 It waits for about 5 seconds, not 15.  Here's the relevant part
 of the timestamped log (the big numbers are seconds since the epoch):
 
   recv(1479853346.806, '[37m\x1b[44mStatus: \x1b[7mRun')

 No, they don't.  I changed the test to run ifconfig -a twice, with a
 delay of 120 seconds inbetween.  The first one printed:
 
 sk0: flags=0x8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
         ec_capabilities=5<VLAN_MTU,JUMBO_MTU>
         ec_enabled=0
         address: 00:1b:fc:9e:0f:b4
         media: Ethernet autoselect (10baseT half-duplex)
         status: active
         inet 10.169.0.2/24 broadcast 10.169.0.255 flags 0x1<TENTATIVE>
         inet6 fe80::21b:fcff:fe9e:fb4%sk0/64 flags 0x2<TENTATIVE> scopeid 0x3
 
 and the second one printed:
 
 sk0: flags=0x8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
         ec_capabilities=5<VLAN_MTU,JUMBO_MTU>
