I think $last_port_assigned would need to be shared between the two modules.  This global safeguard is already a bit
buggy,but not sharing it between modules would be far worse.  Currently, if a node which has a port assigned is
stopped,and a parallel test creates a new node, this global variable prevents the new node from getting the port
alreadyassigned to the old stopped node, except when port assignment wraps around. Without sharing the global,
wrap-aroundneed not happen for port collisions. 

Or am I reading the code wrong?
