Comment(by leif.walsh):

 I can reproduce this on pidgin 2.5.5 (ubuntu 9.04 x86).  With strace, it
 seems that these wakeups are coming from gettimeofday.  Please let me know
 if I can provide you all with some debugging information to get this
 resolved, as I have the following output from powertop, which seems
 unacceptable:

 Top causes for wakeups:
   55.4% (759.0)            pidgin : do_nanosleep (hrtimer_wakeup)
   26.7% (366.3)       <interrupt> : extra timer interrupt
    6.6% ( 90.5)      <kernel IPI> : Rescheduling interrupts
    1.6% ( 22.0)       <interrupt> : iwlagn
    1.4% ( 18.9)            chrome : futex_wait (hrtimer_wakeup)
    1.2% ( 16.9)       <interrupt> : i915 at pci:0000:00:02.0
