Unknown IO port electronic symbol Agree. Looks like the pin would be pulled low during sleep if the transmission gate were not there.

weird "restarts" (but not actual resets?) I'd try an RC snubber rated for 230 VAC across the relay contacts to see if that solves the problem.

AVR0/1/XMEGA Virtual Ports - Confusion You don't need to do anything (except for the usual setting of IN/OUT direction) to enable VPORTs, their behavior is built in.
VPORTA.OUT = value you want on PORTA
VPORTB....

Alternative names for vocabulary research Sounds like you want to use the CPU Cycle Counter. This is a 32 bit counter that increments on every CPU clock cycle and is always available (enabled by default IIRC)....

Sounds like "mouse acceleration" with improvements which certainly predates 2003.

You didn't change the 2V supply while the 5V supply was still active, did you?
