Comment(by drees76 at gmail.com):

 I entered a bit more info in the (now closed) ticket #3800 - there are
 more numbers regarding how often mythwelcome and mythbackend wake up when
 idle.

 The select timeout in mythsocket.cpp looks to be a big offender, that will
 cause any application which uses it to wake up at least 100 times a second
 (default select timeout is 10k usec). Is there any known reason that can't
 be made larger or infinite?

 If I'm reading the code right it seems that the timeout could be made
 infinite (replace &timeval with NULL on line 743) without drawback thanks
 to the WakeReadyReadThread function.

 I'll attach a patch if anyone wants to see if it totally breaks anything
 (I won't be able to test for a couple days).
