Delay Before Going into Sleep Mode

I had been experiencing a thirty second delay when I tried to put my iMac into Sleep mode.

I discovered that after I hooked up a USB modem to receive faxes that I had left the 'Receive faxes on this computer' option checked in the Receive Options of the Fax preferences. Unchecking that box enabled me to go into Sleep mode with no delay.

[crarko adds: USB devices have often been culprits in Sleep problems with Macs for a long time, as indicated in these previous hints. Checking them out is always a good step in troubleshooting problems with Sleep/Wake from Sleep.]
