21c5c73db5 I suppose a SIGKILL or SIGTERM should make a process go about its 
business fast. But the previous situation would allow
"sigblock(sigmask(SIGTERM)); kill(SIGTERM)" to thwart priority policies.

a0bdba3231 always good to think about patches before they're included: 
NEVER pass a "NULL" proc to an ioctl; you never know when a 'real'

32c2dba8da Mike Karels' solution to Andrew Herbert <andrew@werple.apana.org.au>'s 
kern_exit race condition problem.  this is a hack:
	don't vrele() or vgoneall() if we don't have the vnode
	any more.  no vgoneall() is necessary, because if the refcnt
	is zero, there's nobody to take it away from!
a possible "real" long term solution would be to change the extra ref
into a bit in the vnode's flags, and DTRT in the places where the last
ref is killed.  That has some problems, too.

8068dd9add fix from david greenman, davidg@freefall.cdrom.com: 
sosend was attempting to reserve space in an mbuf cluster for a datagram
header and because of bugs in the sosend's mbuf allocation algorithm,
sosend was calling uiomove twice as many times as was necessary. It turns
out that PREPEND does the right thing when a cluster is associated with
an mbuf header, so the datagram header allocation can be defered. This
also ends up additionally consuming one less mbuf for the TCP protocol
because TCP always allocates another header mbuf regardless if space is
available to prepend the protocol header. The net result of this fix is
that unix domain and pipe throughput is increased by a measured 10%.

SUMMARY:
    Here is a patch for a kernel hang that can be provoked with a write
    or send of a negative amount.  The talk program is capable of exercising
    this bug.  This patch also includes a fix for a bug that caused data
    to be delivered to TCP in smaller chunks than desired, and which caused
    TCP to send a short packet when starting up.  Finally, there is a bug
    fix for MSG_PEEK with an oobmark pending.
