This is invaluable for dial-on-demand connections...
In ppp.linkup:
set log -dns -tcp/ip
and in ppp.linkdown
set log +dns +tcp/ip

value.
This has minimal impact here, but if ppp ever needs to frequently
remove timers before they've timed out, it can badly skew the next
item in the timer list without this change.
The correct fix would be to store usecs in `rest' rather than
TICKUNITs, but the math is easier if we just round...
that we adjust that timers `rest' value (with the current getitimer()
values) before using that to adjust the next items `rest' value.
After adjusting that value, restart the timer service so that we've
now got the correct setitimer() values.
I don't claim to own the code and certainly don't want to discourage
people from fixing or updating it.

2048 is big enough as an MTU/MRU, but we need to be able

on the timer queue twice (tick tick tick tick *boom*)
method avoided all race conditions, but suffered from
sometimes running out of buffer space if enough clients
were piled up at the same time.
Now, the client pushes the link descriptor, one end of a
socketpair() and the ppp version via sendmsg() at the
server. The server replies with a pid. The client then
transfers any link lock with uu_lock_txfr() and writev()s
the actual link contents. The socketpair is now the only
place we need to have large socket buffers and the bind()ed
socket can keep the default 4k buffer while still handling
around 90 racing clients.
