It doesn't do a lot--attaches any number of tasks, quiesces them, and asynchronously reports that fact, but there's a test driver and a bit of documentation on general philosophy and implementation.
Forgot to mention it in the doc, but you can try it out by building the test driver and building and installing the module (see the README), starting something simple like bash and running ./froggy-test -t<pid> where <pid> is the bash task. you'll get some stuff, but the important part is where it says "resp buf = "quiescing" That's a round trip from attach->quiesce->asynchronous response.

I'm not sure you realize that what you heard is not what I meant.
