[casper] Linux tools keep crashing

[Suraj Gowda]

Multiple times, after starting a simulation MATLAB will crash and then  
suddenly nothing from that design will work.  So copying the design to  
a new file and trying to simulate does hangs in the "initialization"  
part of the simulation.  Anybody else have this problem and/or a  
solution?

I'm using the RHE5 setup.
