Hi List,

from my understanding of the code, this caveat still exists. And I have the 
same problem with this block as Achilleas.

Johnathan: As you wrote in the cited post that you would be working on that 
after 3.7.0, could you please give an update on the state of work?
How can we support?

Mit freundlichen Grüßen / Best regards

 Stephan Ludwig

AFAIK, pdu_to_tagged_stream is busy-waiting for new PDUs (at least in 
June 2013 it was) and always uses 100% CPU.
