+=head2 Problems on RHEL5/CentOS5
+
+There is a problem with slow performance of certain DBIx::Class operations in
+perl-5.8.8-10 and later on RedHat and related systems, due to a bad backport of
+a "use overload" related bug.  The problem is in the Perl binary itself, not in
+DBIx::Class.  If your system has this problem, you will see a warning on
+startup, with some options as to what to do about it.
