	This is a very basic question, but i'm could'nt figure it out.

I have two tasks Ta and Tb. 
Ta has done a 
	port_allocate(task_self(), &port_A)
then Ta has the receive rights to this port.

I want Tb to send a message to port_A of Ta, so how do i give Tb
the send tights to this port of Ta.

 1. Tasks Ta and Tb are two seperate tasks.
 2. If Tb is a child of Ta. (but Tb is created with a fork(); exec())

How do i use the environment manager, as the env_manager has a
seperate environment for each task.
