just trying to understand what you mean by this. i have to this point been 
looking at having a Froc graph constructed from multiple cells (a tuple of 
Changeable and setter function), and then having each Lwt thread capture one of 
the setters so that it can push a new value into the Froc graph in response to 
external IO. the bit i'm finding mildly tricky at the moment (or was until 
today, which is mostly being about annual performance reviews :/ is managing 
the Lwt thread pool correctly. (ie., calling Lwt_main.run on the right things.)

(a) does this sound sane or am i missing the point?

(b) are you suggesting that each time an input comes in on an Lwt thread i 
should spin off a new process and explicitly hand off resources, in order to be 
completely clear what and where are the resources?  (primarily IO handles and 
such like i guess?)
