I was thinking more at an application level, parse n fields out of the HTTP request then die. But modifying lua to suit would work too I suppose. I don't think there's a general need for this but it might make a handy power patch.

You have to be careful with HTTP header fields too.
That does raise an interesting alternative solution. The string interning logic could optionally detect when a chain of strings had exceeded some limit and then fail the effort to add the string. This is probably only recommended in controlled contexts where one is prepared for the error to occur, but by blocking the problem at the point where we're interning the strings we avoid needing to protect the hash table cases.Mark
