• (ms) removed superfluous eval() in Log4perl.pm, reported anonymously
  on the CPAN bugtracker.
  
• (ms) Added a cleanup() function to Logger.pm which is used by an
  END {} block in Logger.pm to tear down all Loggers/Appenders
  before global destruction kicks in. In addition, Kevin found
  that the eval "" is the cause of an Appender memleak. Moved
  assignment variable out of the eval to plug the leak.
  Added $Log::Log4perl::CHATTY_DESTROY_METHODS, which shows
  what L4p objects are destroyed and when.
  
• (ms) Kevin's idea is in now, on localizing $? in the L4p global END {}
  block. It prevents logdie() et. al from exiting with unwanted
  exit codes when global cleanup / global destruction modifies $?,
  as seen by Tim with the Email appender.
  
• (ms) Dave Viner dviner@yahoo-inc.com added isLevelEnabled() methods
  as aliases to is_level().
