Slow to Sleep Power Mgt. App - How can it be reset?

I posted the following some time ago and it was never answered. My iMac is really slow
to sleep (sometimes 20 to 30 seconds) from clicking on Black Apple/Sleep until it sleeps.

The last time this happened I had a big file hung in a print queue and clearing it help. I
do not have anything in the print queue now but when I run the the CNET tip to listed below
I get all kind of stuff associated with the Apple powermanagement application

* Domain: applicationresponse.slowresponse
- Message: Kernel configd com.apple.powermanagement.applicationresponse.slowresponse 10504 ms

and

I have no idea how to reset the Apple Power Management. Some help will
be appreciated. I wonder if there is a prefs file that could be trashed

A friend suggested I read a MacFixIt note in CNET titled Snow Leopard slow to sleep

For users experiencing this issue, you can narrow down the cause of the slow shut down using a simple Terminal command. Open Terminal and enter:

pmset -g log

The "Signature" with the longest "Response Time" (in ms) should be the first program to look at. Users should be sure they have updated all their third party applications and plug-ins, especially after updating to Snow Leopard 10.6.2, to ensure the best compatibility.

I did and and there were several small and a few big items but I have no idea what I should
do about it???
