So, i've read some of the previous postings on this, and it surely
sounds like that has happened to me. I read a tip about adding noise to
critical sections of the patch, but can't really figure out how much and
in what kind of situations. It would be great to see a patch which does
this.
Otherwise, does anyone have any other practical tips in how to design a
patch to make it immune against the slow and accurate mode?
thanks!
Johannes
