In the current state of the cpu emulation, it would first need some 
cleanup / merging of some code ; each time there's a memory read/write, 
it goes through several levels of indirection, blitter or dma can also 
use some "shortcuts" in the different functions, so it's not really a 
good idea to do it at the moment.
It would make sense once we had support for "fast" ram with different 
cycle access as  this would imply to rethink the memory's organisation.

It would add an overhead, whether it's a big one or not depend on the 
power of the computer used to do the emulation  (but it would imply a 
check on each read/write to see if further debugging function should be 
called or not, so that's an overhead)
