I did both. In the core functions I compare the calling thread with the tcpip 
thread ID.
In the sockets I store for each socket created with socket or accept the thread 
that created the socket and compare it in the other socket functions with the 
calling thread ID. So I can be shure that a single socket is not "used" by 
different threads (i.e. select in one and send in the other). At least in the 
past things like that caused problems.
