Yep, that's a bug
perldoc Apache2::RequestUtil
# get the global request object (requires PerlOptions +GlobalRequest)
$r = Apache2::RequestUtil->request;
which means u need GlobalRequest in apache config, which I'm not a big fan
of. Better raise a bug in cpan rt for this module and get Tatsuhiko to fix
it. By the looks of it, this hasn't been updated in a while.
personally I don't really see a need for Apache::Singleton::Process unless
there needs to be a module for consistency in Apache:: namespace,
class::singleton does pretty much the same job. If you need a per-request
singleton meanwhile, cookup something quickly of your own that uses apache
pnotes to store the instance
perldoc Apache2::RequestRec
