Making PID_MAX tunable sounds like a fine idea. You get bonus points for looking forwards rather than backwards and retrofitting the userland tools for 6-digit pids. ;-) > I think FreeBSD 1.1 compatibility is obscure enough that there's no > need for it to work in out of the box (i.e. GENERIC) at the cost of > increased complexity in non-obscure configurations.

I think COMPAT_43 exists mostly to cover up a bunch of stuff that ought to have been nixed or fixed a long time ago, not for actual 4.3BSD compatibility. For instance, COMPAT_43 is still required to get the old socket interface that linux.ko requires.
