Public bug reported:
goa-daemon is causing a lot of wakeup events on raring. I'm seeing ~2
wakeups a second which seems excessive. What is it doing?
I've straced it and I see the following:
Process 2881 attached - interrupt to quit
restart_syscall(<... resuming interrupted call ...>) = 1
ioctl(9, FIONREAD, [512]) = 0
write(4, "\1\0\0\0\0\0\0\0", 8) = 8

revents=POLLIN}])
poll([{fd=4, events=POLLIN}, {fd=5, events=POLLIN}], 2, 10) = 1 ([{fd=4,
revents=POLLIN}])
read(4, "\1\0\0\0\0\0\0\0", 16) = 8
poll([{fd=4, events=POLLIN}, {fd=5, events=POLLIN}], 2, 10) = 0 (Timeout)

lrwx------ 1 king king 64 Nov 21 22:20 9 -> anon_inode:[eventfd]
so it seems quite busy on an eventfd for some reason.
Anyhow, can we see if we can reduce this excessive amount of wakeups?
I'd hate to see this chew up my battery for no reason at all.
