public class JDBCDriverUnloader
extends java.lang.Object
implements java.lang.Runnable, java.lang.Iterable<java.sql.Driver>
This class gets specially loaded directly in the JRubyClassLoader so that
we can unregister all JDBC drivers that were loaded/registered. It gets
invoked as part of the Ruby runtime tear down.
