Ok will do, will wait and see. As a rhetorical question, what is wrong 
with task.getSomeRegisterFunctionName("eax") as a general helper 
function? Why do I need to know (ptrace buffer?) offset and length to 
access a register? Is this because register access is being move to the 
task from the ISA? Just trying to get a sense of where this refactor is 
going.
