We have found that Gaussian does not clean up nicely so in our epilogue 
script we run an ipcs and clear out any Gaussian shared memory segments, as 
identified by the owner.

You are right, eventually the machine consumes itself. All current 
processes are running just fine, so long as they do not request any more 
memory. :)
