You can certainly add select support to a proc file. It is doable. Odd but doable.
Odd, however it could be quite useful for /proc/${pid}
It might even lead to a nice solution to the problem of debugging threaded applications. Here a lot of the problems with gdb getting things right have to do with reparenting and how thread libraries implement things internally, signals, what have you.
When you can do selects on /proc/${pid}/debug or whatever, a lot of the "what should we do if xxx" questions then have answers.
