time now to break with the past: do not write the PID in the first note.
Rationale:
1. [impact of the breakage] Process IDs in core files serve no immediate
purpose to the debugger itself. They are only useful to relate a core
file to a process. This can provide context to the person looking at
the core file, provided one keeps track of this. Overall, not having
the PID in the core file is only in very rare occasions unfortunate.
2. [reason of the breakage] Having one PRSTATUS note contain the PID,
while all others contain the LWPID of the corresponding kernel thread
creates an irregularity for the debugger that cannot easily be worked
around. This is caused by libthread_db correlating user thread IDs to
kernel thread (aka LWP) IDs and thus aware of the actual LWPIDs.

that get certain types of control messages (ping6 and rtsol are
examples). This gets the new code closer to working:
1) Collect control mbufs for processing in the controlp ==
NULL case, so that they can be freed by externalize.
2) Loop over the list of control mbufs, as the externalize
function may not know how to deal with chains.
3) In the case where there is no externalize function,
remember to add the control mbuf to the controlp list so
that it will be returned.
4) After adding stuff to the controlp list, walk to the
end of the list of stuff that was added, incase we added
a chain.
This code can be further improved, but this is enough to get most
things working again.

quite some time, and has been extensively tested on i386 and sparc64. It
shows measurable performance gains in many circumstances, and few negative
effects. It would be nice in t he future if adaptive mutexes actually went
to sleep after a certain amount of spinning, but that will require quite a
bit more testing.
