Until the window is filled vertically, the process enters some loop. In
analyzing syscalls, it's a half dozen clock_gettime()s and then a rather
expensive poll() of a socket along with a recv() that fails. Loop about
200 times per second.
12:13:37 recv(8, 0x8a19060, 4096, 0) = -1 EAGAIN (Resource temporarily
unavailable)
12:13:37 clock_gettime(CLOCK_MONOTONIC, {256453, 277724784}) = 0
12:13:37 poll([{fd=6, events=POLLIN}, {fd=8, events=POLLIN}, {fd=12,
events=POLLIN}, {fd=16, events=POLLIN}, {fd=3, events=POLLIN}], 5, 0) = 0

12:13:37 clock_gettime(CLOCK_MONOTONIC, {256453, 277835655}) = 0
12:13:37 clock_gettime(CLOCK_MONOTONIC, {256453, 277924856}) = 0

Bug description:
This may have started since I upgraded my system to 12.04, it was
certainly a recent development at around that time. I am using
empathy for IRC only, connected to four channels on two servers,
though even disabling all accounts does not change this. The empathy-
chat process is very consistently at 9% CPU, with spikes at 10% or
higher from time to time. I have tested this on mobile broadband,
wifi and ethernet.
