The sematics of MPI for a single sequential process is defined. When I 
mentioned multithreading, I assume that the issue must be considered
from the following angle:

	1) Translate all possible permuatation of orderings of send() 	
   	   and recv() into sequential MPI-1 programs.
	2) The multithreaded program is "safe" if all the sequential
	   ones defined in 1) is "safe"

Is this reasonable?
