Thanks for your feedback. As I'm running in production I think I may 
downgrade to Perl 5.8.9 (I have the flexibility to do this now - this is 
one of the reasons why I'm looking to replace the RHEL-bundled Perl 
RPM-based install with a custom version) and wait for these changes to 
work their way through in a stable release.
