That's useful to know.   Since I'm playing, I hacked ddb directly.

So far the only notable tweak I've made is to add a prompt parameter
to db_readline.  Otherwise I found myself looking at:

db> lua
db>

and wondering if my code worked :-)   However, before worrying about
that, my lua main-loop should be inverted (so it is closer to lua.c) -
my proof-of-concept followed what's found in the book.

"Going forward", the most interesting thing will likely be hacking
(bypassing) ddb so that events such as breakpoints and watchpoints are
directly pushed (injected) into a Lua instance.  So far, the reverse,
pulling stuff like memory into Lua has proven relatively painless
(which reminds me, how do I silently detect that db_read_bytes
failed).

Oh, it might be nice if readline behaved more like readline :-)  It
doesn't seem to under QEMU.
