Comment (by fasta):
I don't really believe in the "too much overhead" argument, until there is
a clear analysis, which demonstrates this. It's often possible during
debugging to create a small test case (one which does not take a long time
to run). So, even recording all the state changes in the machine would be
possible. I also argue that this should be the default. If it is too slow,
people would just use some approximation (like is currently being done).
