This comment was specific to building and testing GCC.  It currently 
takes slightly over
24 hours to build and test GCC trunk on my c3750.

Based on my testing, it's no longer necessary to try 5 times before 
succeeding with rp3440.
I agree that the C37XX machines are very stable and don't suffer from 
the SMP/cache
issues present in the servers.  If the ring above could be arranged, 
that would be excellent.
