Not sure. Does ppp spawn off another process to do routing changes ?

I diffed the source to ppp from 10 vs 11 and nothing has really changed.
 Perhaps routing API changes that ppp was relying on ?

23810 is ppp as its currently running

I would re-run ppp under ktrace to make sure while having "route
monitor" running around.
Then compare pids with kdump output.

It seems so.
