The details are hidden in the DB_COMMAND(cmd_name, func_name) and
DB_SHOW_COMMAND(cmd_name, func_name) macros. DB_COMMAND() adds to
the top-level ddb command table and DB_SHOW_COMMAND adds to the
`show' subtable. Most external commands will probably be `show'
commands with no side effects. They should check their pointer
args more carefully than `show map' :-), or ddb should trap internal
faults better (like it does for memory accesses).
The vm ddb commands are temporarily unattached.
ddb.h:
Also declare `db_indent' and db_iprintf() which will replace vm's
`indent' and iprintf().
/usr/bin/lock can be used to lock a terminal much like xlock does
for your X-windows session. Problem is, /usr/bin/lock cannot lock
your terminal indefinately. Rather you must specify a timeout
value, after which, your terminal is unlocked and become unsecured.
I have added a ``-n'' no timeout option to /usr/bin/lock
Currently the only way to get this functionality is to use a huge
timeout value and hope it is long enought (in time). This method
also requires you to know the maxium number of minutes you are
allowed to specify.

Saved a few bytes by copying `dosdev' and/or `name' to local variables.
This optimization (for dosdev) was done in one place before but this
was lost in the devread() cleanup. This optimization (for dosdev)
can almost be done by bogusly declaring dosdev as const, but gcc still
often space-pessimizes code like the following:
extern const int dosdev; ... foo(dosdev); bar(dosdev);
gcc often doesn't bother to copy dosdev to a temporary local because
the local would have to be preserved in memory across the call to
foo(). OTOH, for
extern int dosdev; ... auto int dosdev_copy = dosdev; ...
foo(dosdev_copy); bar(dosdev_copy);
the copy must be made because foo() might alter dosdev.
the pointer to the string "/kernel". This pointer was once only
statically to once save space, but it has had to be dynamically
initialized for some time, so the static initialization just wastes
space. The string gets moved to the text section, so the actual
savings may be negative due to padding.
instead of 0 if there is no input.
pcvt_drv.c:
Partially fixed pccncheckc(). It returned a boolean value instead of
the character that it fetches from the input fifo (if any). I think
it still discards characters after the first for multi-char input.
instead of 0 if there is no input.
syscons.c:
Added missing spl locking in sccncheckc(). Return the same value as
sccngetc() would. It is wrong for sccngetc() to return non-ASCII, but
stripping the non-ASCII bits doesn't help.

or __pure2 where it wasn't already done, except in math.h where use
of __pure was mostly wrong.

(Immutable targets can't be renamed without opening a window when
neither the source nor the target is immutable. Perhaps there
