+ * ConnectionHook keeps track of all open Connections. It's used only in

+ *
+ * This is a singleton object ;-)
+ *
+ * How it works: This is an initiated but un-started Thread. When it's created,
+ * it registers it'self with the Runtime.addShutdownHook() method.
+ *
+ * When a Connection is made, two static methods in org.postgresql.Driver are
+ * called. For pre JDK1.3 these are noops, but for 1.3+ ANT adds calls to
+ * methods in this class, which add/remove it from an ArrayList.
+ *
+ * Now when the VM terminates it starts this thread, which then Itterates
+ * through the ArrayList and closes each Connection.
+ *
+ * Obviously this doesn't trap things like Runtime.halt() or SIGKILL etc, but
+ * this captures 99% of all other forms of VM termination.
