Unfortunately, system calls get bounced back to the main node.  This
creates an IO bottleneck (all file reads/writes are done on the main
node, no matter where the process got migrated to).  

But for the (admitedly sizeable) class of problems where all one does
is chug on data for a while, then write results, mosix is indeed
pretty cool.
