Or maybe we got scared of threads :)

I would try replacing the thread with add_timeout function. Then you do
not have to use threads and can use the same timing support that rest of
Radiator uses.

grep for add_timeout in Radius/ directory for examples. The function
lives in Select.pm.

Hard to say. If you can replace threads with add_timeout, then we could
at least know if the leak is a side effect from using threads or not. I
really do not know how Perl's memory management works with threads.

Thanks!
