I don't know if this is much of an insight ....

If I run "sleep 10000" on a console, using lsof I find the following
extra file descriptors open:
sleep     12640      paul    4u     unix 0xffff88009d543180       0t0
 39745 socket
sleep     12640      paul    9u     unix 0xffff8800b8539e40       0t0
 39985 /tmp/ksocket-paul/kdeinit4__0
sleep     12640      paul   10u     unix 0xffff88009d543180       0t0
 39745 socket
sleep     12640      paul   12u     unix 0xffff88009d543180       0t0
 39745 socket
sleep     12640      paul   13u     unix 0xffff88009d543180       0t0
 39745 socket
sleep     12640      paul   14u     unix 0xffff88009d543180       0t0
 39745 socket

These match up the the AVC denial from SELinux. Further playing with
lsof shows that the earliest processes with these open is kdeinit4.

Apologies if I'm teaching you to suck eggs.
