I wasn't suggesting to write everything from scratch.

The idea was to start with a clean slate, but moving over existing code
where possible as you go on (re)implementing the individual bits of

So you would fist implement a basic skeleton, which only creates an
empty directory for each existing pid; then you add for example the
program arguments file; then the state; and so on... Always using the
existing implementation as reference, and borrowing code whenever it's

The great advantage of this approach is that you get small, well defined
steps you can complete one after the other, instead of being faced with
a single large porting effort in the beginning, having to deal with a
lot of code you are not familiar with...

If I correctly understand your description, that's more or less what I
had in mind :-)
