    Furthermore, this problem is only going to become worse. There are
many things that can be done to improve the performance of processors,
but they are only starting to be put into commercial production because
C is a very poor computational model for the underlying architecture.
Future processors are going to require you to write highly parallel
code, something that is virtually impossible in C because it has no
notion of concurrency.
