[omniORB] Re: Testing OmniORB4 for memory leaks on Linux RH9

[Sean Parker]

Re: mtrace of ORB_init-then-orb->destroy:

I did some 'commenting-out' in the ORB_init mehod, and
found most allocation-danglers dissappear when the
omniOptions-calls were gone - then even more go away when I
comment-out matching interecptor attach/detaches. 

Is the community open to me submitting a future patch that
begins to fix these leaks (after more digging and
uncommenting of course)? (it seems reasonable to expect an
ORB-init followed by orb->destroy would leave no dangling
memory, regardless of realtiy of the scenario)

Cheers 
  Sean
