Package: dirmngr
Version: 1.0.1-3
Severtity: normal
dirmngr is seen often in top of powertop results on a idle kde4
system. Looking at strace, looks like dirmngr has select() timeout
based loop. That is bad in power managment perspective. CPU can't
dynamically sleep long periods when applications wake it up..
