I tried myself too.  A few of these seem to come from sugar-shell, the
vast majority are from the datastore-service.

A quick strace run reveals that the datastore-service process sleeps
for 2.5ms in a tight loop.

This one comes from arch/i386/kernel/mfgpt.c, but I dunno why and I have
no time to investigate it soon.  Hopefully somebody can tell us without
the need to dig in the code.
