One way to approach that would be to have the delayed instance check
for the existence of a "never mind, I already did it" file after the
delay has expired.  That is, assuming it's OK to have this delayed thing
sleeping in the background for a while before it wakes up, finds the file,
removes it, and terminates itself.
