I'm willing to have this patch lowered to a P3. I've discovered that by using jacorb.implname, I can prevent all of this excess stack trace dumping from showing up. To me, it's a workaround because I'm not using implementation repository. Our application was not originally desiged to use the Imr, and we don't plan on rewriting it's handshaking to enable it to work in this environment. JacORB is making an assumption that if you have multiple VMs running Corba on the same machine, then you should be using ImR. I don't think the code should require this. Rather, it should only enable it.
