I know we are going OT, but I also want to understand this;
what about:
function mymodule_complex_calculation() {
static $cache;
if (isset($cache)) {
return $cache;
}
// Otherwise we need to perform our calculations
// ...some complex calculation that returns
$cache = complex_calculation();
return $cache;}

You are saying that if I instantiate a variable in "mymodule_impersonate()"
it will not be available in "mymodule_unimpersonate()"?
