I am experiencing similar behavior.  ktrace(1)/kdump(1) shows:

   877 nautilus 0.000005 CALL  poll(0x8064d3f10,0xe,0)
   877 nautilus 0.000006 RET   poll 0
   877 nautilus 0.000006 CALL  gettimeofday(0x7fffffffe4a0,0)
   877 nautilus 0.000005 RET   gettimeofday 0
   877 nautilus 0.000008 CALL  ioctl(0x3,FIONREAD,0x7fffffffdc9c)
   877 nautilus 0.000005 RET   ioctl 0
   877 nautilus 0.000006 CALL  gettimeofday(0x7fffffffe4b0,0)
   877 nautilus 0.000004 RET   gettimeofday 0

This pattern repeats endlessly.  I did googling and found this:

Interesting stuff...  Unfortunately I don't have time to investigate 
what's going on.  If anybody is interested, I think this is good 
place to start.

Thanks,
