+=head1 BUGS
+
+With mod_perlB<2>, any new request will change the cwd for all processes.
+This means that if you're running files from multiple directories,
+you I<should not use the current path> for it may change at any time.
+
+The bug has been confirmed with at least mod_perl 2.0.2/3/4 on Apache 2.2.3/8.
+Using this backend on Apache2 is extremely discouraged until this is fixed.
+Instead, L<the FastCGI backend|PLP::Backend::FastCGI> is recommended.
+
+Apache1 does not show any problems.
