If it is fairly trivial for you, could you please take it at feature request? :-)
I mean, to extent this for delaying dhcp replies so that perl code running under rlm_perl
can return needed delay to the core?

I would be happy to test 3.0 from github under our severe load then.

And add an option to note significant changes of thread_pool.num_queued to the log, too.
For example, log this value if it has increased or decreased with configurable number of percents
comparing previously logged value.
