In article <address@hidden> you write:

``... In Standby mode, the Crystal/Resonator Oscillator is running
while the rest of the device is sleeping. This allows very fast
start-up combined with low power consumption. In Extended Standby
mode, both the main Oscillator and the Asynchronous Timer continue to
run.''
>The OC1B output is the same, though.
No idea whether the CPU/IO clock is halted in a synchronized way or
not, but it's quite possible. You might try making a support call to
Atmel for clarity.
By turning PWM off before going asleep, and explicitly setting the pin
to low, you'll certainly be on the safe side.

Never trust an operating system you don't have sources for. ;-)
