Perhaps you could try opening a socket connection such that process 1 sets
up a service and the other process(es) open a simple client connection to 
process 1's service. Do some communication, figure who usmalloc'd what,
then close the connection and await a new one. This will serialize multiple
client starts into the common area. The rest of the communication could be
done via the shared memory.
Should work.
