Ah.... Found this in /sys/netgraph/ng_base.c. Yes, it does seem to
have a pool of worker threads. This is good. It means that if
there's a single thread or single CPU bottleneck for a busy PPTP
server, it would not be the netgraph traffic but rather the one
process handling the TCP control connections for the PPTP sessions.
I'll give it a try and see if this causes any problems.
Still wondering about that boot time message, though.
