Nice, but Your post lacks the license you have for your code. Is it MIT?
Could you please add it? Makes it easier to reuse your code.

If I have a C function called by Lua. It has an upvalue and I'd like
to change it's value. Possible?
static int closure_that_has_upvalues( lua_State* L )
{
...
// how can I change the value of, say, the upvalue at
lua_upvalueindex(1)?

Box the actual value inside a table and then set the table as the upvalue.

An upvalue index is just like a regular stack index, so you can use
lua_replace with it:
lua_newtable(L);
lua_replace(L, lua_upvalueindex(1));

Hi,
I should apologise for the slowness of lua-l this week. Starting Monday, a
botnet was using a cracked password of one of my users' mail accounts to send
vast quantities of spam through Pepperfish.
Fortunately the checks and balances I have in place stopped the outgoing queue
pretty quickly; but I still had to deal with incoming mails at the rate of 10
to 40 per second, and combine that with the huge queue which took ages to clear
down, it slowed lua-l for probably the majority of Monday and a bit of Tuesday
until it was all clear.
I have now reached the point that I'm confident that it's not recurring and so
I thought I'd best let everyone know so they don't worry about it.
Thanks,
Daniel.
