This document should now serve as a reasonable tutorial for the
modern POSIX shell. Comments and additional fixes for mistakes I may

40cf6f3659 Remove uarea swap-out functionality: 
- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code.  Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.

Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).

Discussed on <tech-kern>, reviewed by <ad>.

4515588628 Fix the "dne" handling and chmod behaviour properly: values of dne 
need to be on a stack instead of being a single variable since
directories are processed depth-first.  Otherwise dne randomly
depends on the previously processed entry.

This fixes both chmod of non-created directories (they used to be
chmod'd even when not created if their last child element did not
exist in the target subtree) and a "foo exists" bug exposed by my
last commit which removed directory sorting.

c817a14b24 Remove fts sorting. It was originally put there to copy files 
before directories since files (usually) are in the same cylinder
group and subdirectories aren't.  However, this mostly changed with
the new ffs dirpref algorithm in 2001.

No sorting has two effects:
1) copy appears to be somewhat faster (e.g. on my laptop cp'ing build
   objdir to tmpfs is 7% faster after the change)
2) source file parameters no longer get randomly shuffled due to
   fts doing an unstable sort of them.  this means that
   "cp 1 2 3 4 dest/" will copy the files in that order instead
   of e.g. 3 4 1 2.

fcc023545e - add new RLIMIT_AS (aka RLIMIT_VMEM) resource that limits the total 
address space available to processes.  this limit exists in most other
modern unix variants, and like most of them, our defaults are unlimited.
remove the old mmap / rlimit.datasize hack.

- adds the VMCMD_STACK flag to all the stack-creation vmcmd callers.
it is currently unused, but was added a few years ago.

- add a pair of new process size values to kinfo_proc2{}. one is the
total size of the process memory map, and the other is the total size
adjusted for unused stack space (since most processes have a lot of
this...)

- patch sh, and csh to notice RLIMIT_AS.  (in some cases, the alias
RLIMIT_VMEM was already present and used if availble.)

- patch ps, top and systat to notice the new k_vm_vsize member of
kinfo_proc2{}.

- update irix, svr4, svr4_32, linux and osf1 emulations to support
this information.  (freebsd could be done, but that it's best left
as part of the full-update of compat/freebsd.)


this addresses PR 7897.  it also gives correct memory usage values,
which have never been entirely correct (since mmap), and have been
very incorrect since jemalloc() was enabled.

tested on i386 and sparc64, build tested on several other platforms.

thanks to many folks for feedback and testing but most espcially
chuq and yamt for critical suggestions that lead to this patch not
having a special ugliness i wasn't happy with anyway :-)
