Before even posting this thread I ran PowerTop, and my CPU wakeups were reduced over leaving MSCIM running. Here's an example powertop output:

Code:
Powertop 1.13.3
Sleeping for 11 seconds before sampling
Collecting data for 30 seconds
Sample interval was 00m 30s 28717us

Clock activity breakdown at end of period

--------+---------------+---------------+------------------
   core |          SDRC | HSOTGUSB_IDLE |      OMAPCTRL 
        |     MAILBOXES |
   wkup |          GPT1 |       32KSYNC |         GPIO1 
        |
  ckgen |          CORE |          PERI |           96M 
        |           48M |           12M |           54M

        |         GPIO5 |         GPIO6 |

Total wakeups  3065, 102.2/s | IRQ 2959,  98.6/s | Timers  106,   3.5/s
HW wakeups       55,   1.8/s |     Real gp_timers expired   66,   2.2/s
Now, obviously the overhead of dbus-scripts will exceed the resource usage of some, maybe most, processes/applications. That does not mean that there are no use cases for this idea.

i want your opinion guys
does this save power or not ? (at least a bit)
