it should work to add back to the queue from same loop, but then
practically you get infinite loop until the queue gets empty.

There is a function that returns the size of the queue -- mq_size() --
see the readme of the module. Then you can use a variable to increment
as you fetch and exit the while loop when you reach the size. You should
use the latest branch 4.2, as I just reviewed the mq_size() and had an
issue when the queue was empty (0 cannot be a return code for a function
in kamailio.cfg, so now it returns -1 if the queue is empty).

Cheers,
Daniel
