Hi Joe,

It is a nice idea. Once fired when the PIC enters the SLEEP it will probably delatch due to current less than the minimum latching current. But I personally feel it is not necessary as it adds to the hardware cost and also causes power loss (disipation). Not recommended for a battery powered low (ultra???) current equipment. With the 10F206 it is possible to shut it off into ultra low power mode by software only without any modification to the existing circuit and PCB.

Rixtalbert I hope by this time you have already implemented what jerson suggested. If not then post your code or usage of the peripherals --> Interrupts, Pin Change, Comparator etc so that an actual code snippet can be thrown.
