this is a common problem when linking on machines that don't have a lot
of memory: the machine starts swapping and the link takes forever.  Try
doing an optimized build instead: the object files are much smaller, so
it doesn't put so much strain on your machine.

Ciao, Duncan.

  When it reaches this point, almost no CPU/IO activity
