 If I pass the output of isc-sysinfo to another process via a pipe
 and that process doesn't consume all input from sysinfo, sysinfo
 itself dies with an uncaught exception of IOError (Broken pipe):

 {{{
 % isc-sysinfo|head -1
 ISC Sysinfo tool
 Traceback (most recent call last):
   File "/home/jinmei/opt/bin/isc-sysinfo", line 136, in <module>
     main()
   File "/home/jinmei/opt/bin/isc-sysinfo", line 121, in main
     write_value(f, '%s', s.get_net_connections)
   File "/home/jinmei/opt/bin/isc-sysinfo", line 42, in write_value
     out.write(fmt % value)
 IOError: [Errno 32] Broken pipe
 }}}

 This is not really grace.
