Description:
------------
When restore_exception_handler is called in a finally block, the *restored* exception handler handles the exception.  I would expect the exception to be fully resolved before restore_exception_handler takes effect.

The PHP documentation states "Code within the finally block will always be executed after the try and catch blocks, regardless of whether an exception has been thrown, and before normal execution resumes."

Test script:
---------------
<?php
function handler1($e) {
  echo "\nhandler1";
}

function handler2($e) {
  echo "\nhandler2";
}

set_exception_handler('handler1');

set_exception_handler('handler2');

try {
  throw new Exception(); // 'handler1' is displayed.  Expected: 'handler2'
}
finally {
  restore_exception_handler();
}
