I am using MPICH 1.4.1p1 with ch3:sock device, and have noticed that it is vulnerable 
to being scanned by nmap.

With a rank sitting on an MPI_Recv, if you use nmap to scan the rank's listen ports
with a command like:

nmap -p <port> -T4 -A -v <host>

MPI_Recv with detect an error and exit.

Has this been fixed in newer versions of MPICH?
