Well, I'm working on reimplementing the pydevd debugger to use it.

The general idea is that pydevd will be able to use that API instead of relying on sys.settrace (which was perceived as slow in general -- pydevd got by because it had a bunch of tricks to just trace the needed contexts but implementing a fast debugger in Python with it is pretty hard).

My initial results are still mixed -- i.e.: on some cases it's definitely faster -- such as when tracking exceptions, but at this point in all other scenarios it's still slower (it's pending a few profiling sessions and I already have some ideas on where to improve), but I'm still not sure it'll ever be as fast as the version that can hook into the python frame eval and change the bytecode for the function to add programatic breakpoints... time will tell (but that approach is also very hard to keep up to date on new python releases, so, I'll probably end up deprecating it as I don't have enough time/resources to keep it up to date).

Anyways, I have most tests already passing, but I have to do a few profiling sessions before the initial release. I guess there's no much point in saying: here's a new version of the debugger using sys.monitoring -- does the same but is slower ;P
