d636a8b9cb On MP, exit postsig() when another LWP has already handled the signal while 
this LWP was waiting for the kernel lock.

9f9d44127e Remove part of a very old change that caused NFS to not enforce socket buffer 
limits.  No idea why it was done in the first place.

Don't remember who reported this, but I think it was yamt.

- factor out common code.
- don't stop searching before the target.
- touch the correct object.
- validate the argument before the loop otherwise we need to roll back.

ea5ec0212d add kernel part of concurrency support for SA on MP systems 
- move per VP data into struct sadata_vp referenced from l->l_savp
  * VP id
  * lock on VP data
  * LWP on VP
  * recently blocked LWP on VP
  * queue of LWPs woken which ran on this VP before sleep
  * faultaddr
  * LWP cache for upcalls
  * upcall queue
- add current concurrency and requested concurrency variables
- make process exit run LWP on all VPs
- make signal delivery consider all VPs
- make timer events consider all VPs
- add sa_newsavp to allocate new sadata_vp structure
- add sa_increaseconcurrency to prepare new VP
- make sys_sa_setconcurrency request new VP or wakeup idle VP
- make sa_yield lower current concurrency
- set sa_cpu = VP id in upcalls
- maintain cached LWPs per VP

1b4f540b78 Look at _UC_STACK to decide whether the process' SS_ONSTACK state needs to 
be updated.  (This is needed to be compatible with how pre-SIGINFO signals
operated.  If you siglongjmp out of a signal handler, the SS_ONSTACK state
needs to be cleared.  This commit restores that functionality).

471ef5f249 once exit1() releases big kernel lock, the struct proc can be freed and 
re-used by another cpu immediately.  in that case, lwp_exit2() will
access freed memory.  to fix this:

- remove curlwp from p_lwps in exit1() rather than letting lwp_exit2() do so.
- add assertions to ensure freed proc has no lwps.

06107df871 Modify pool page header allocation strategy as follows: 
In addition to current one (i.e., don't wast so large part of the page),
- if the header fitsin the page without wasting any items, put it there.
- don't put the header in the page if it may consume rather big item.

For example, on i386, header is now allocated in the page for the pools
like fdescpl or sigapl, and allocated off the page for the pools like
buf1k or buf2k.
