We could have such a feature, but how to implement it?  If we use a
timer for that, the timer itself will drain the battery.  And if defer
it to the next invocation of the bytecode, we might never compile,
because who can guarantee that the laptop is on AC when some arbitrary
bytecode is executed?  Any other ideas?
