Do you know if this will actually work with IRIX? 

I was under the impression that jobs which required a license manager 
could not be checkpointed (or more correctly, they could not re-aquire
the connection to the license manager upon restart). The sgi license
manager has been modified to take account of this, but other products
which don't use the sgi license manager (such as IDL) cannot be 
successfully checkpointed.
