Bug description:  Request 'finally' support for exceptions

Description:
------------
PHP 5 has specifically decided not to support 'finally'. Why?

This is one of numerous cases why finally is useful:

mysql_query("LOCK TABLES mytable WRITE");
try {
  // ... do lots of queries here
} finally {
  mysql_query("UNLOCK TABLES");
}

You need to use UNLOCK TABLES otherwise your tables won't get unlocked
when an exception is thrown. This is especially bad if you use persistent
connections.

It is possible to emulate finally using try/catch but this introduces code
redundancy and may create inconsistent code:

mysql_query("LOCK TABLES mytable WRITE");
try {
  // ... do lots of queries here
  mysql_query("UNLOCK TABLES");
} catch(Exception $e) {
  mysql_query("UNLOCK TABLES");
  throw $e;
}
