I agree... but I hope there would be something like Unix::Proc, too...

Right... but not all people use perl APIs instead of shell scripts
either. My idea was to extend the existing mechanisms with tiny bits,
not creating a whole new thing. And doing work like making libproc a
stable interface is simply to "much" unless we find someone who is
employed to do the work (e.g. someone who has really the time to work on
it...) ...

Backwards-compatibilty can be maintained via the way how the current
/usr/bin/ksh links it's builtin commands to standalone tools, for
example /usr/bin/ulimit is a shell script which looks like this:
-- snip --
#!/bin/ksh -p
#
#ident "@(#)alias.sh 1.2 00/02/15 SMI"
#
# Copyright (c) 1995 by Sun Microsystems, Inc.
#
cmd=`basename $0`
$cmd "$@"
-- snip --
The same stuff could be done for the procsh idea, either looking like
this...
-- snip --
#!/bin/procsh
cmd="$(basename $0)"
$cmd "$@"
-- snip --
... (assuming we create a frontend called "/usr/bin/procsh" which loads
the ptools builtins from /usr/bin/libproctools.so.1 by default)
or...
-- snip --
#!/bin/ksh93
cmd="$(basename $0)"
builtin -f /usr/bin/libproctools.so.1 "${cmd}"
$cmd "$@"
-- snip --
(assuming we only create a library called /usr/bin/libproctools.so.1
which contains the builtins commands).
A 3rd option is to create binary wrappers which call directly the
matching |int b_nameofproctoolcmd(int ac, char *av[], void *context);|
from |main()| which would skip the whole Shell_t creation overhead.
