desktopcouch-service is polling at ~9.9Hz

[Colin Ian King]

Running Precise with all of today's updates I'm observing that the desktopcouch-service is polling at about 9.9Hz, running strace on the process shows:

poll([{fd=10, events=POLLIN}, {fd=11, events=POLLIN}, {fd=3, events=POLLIN}, {fd=17, events=POLLIN}], 4, 101) = 0 (Timeout)

..multiple times.

This 101ms poll is timing out, so we are effectively in a 9.9Hz busy loop. This is consuming power and will reduce battery life on laptops.

It's in universe and not installed by default any more, so low priority for u-power-consumption.

This is the same bug as the syncdaemon issue, as desktopcouch-service is also using a twisted glib2reactor.
