True.  It clearly shows that it was originally written for a very special 
platform (Sparclet, I think) and was designed accordingly.  Certain 
aspects of how breakpoint.c handles watchpoints cannot be understood 
without having this in mind.  For example, why on Earth are 
software watchpoints and hardware watchpoints handled differently from 
read and access watchpoints? why are hardware breakpoints treated like 
normal breakpoints instead of being akin to watchpoints? etc., etc.
