You are right............. it was really of not much success !!

As i mentioned in my other mail........ that i cud not attach the shared
memory segment of 8gb twice...
v.i.z i was able to use only one segment of 8gb... and when i tried to
attach a different segment( i.e with different shimid)
to a different process, i got segfault....
Cud not understand why...!! Is n't 64 bit machine capable of addressing 512
GB of VMA !!
