   IMHO, I dont think such a mechanism is needed.

   I think that is not a problem too. We at such a condition, should have 2 threads, one to block on socket, and another handles all other messages from os, other processes...... If you are really intersted in the thread conditions, you have to poll them by yourself, because there is no such a generic mechanism on every platform and it is rearly used.
 
   IMO, thread model is used to simplify your design. One thread should take one resposibility and one only.
