This is probably the first mention on this list.

I don't see any use in my working on this, because:

a) it opens up a new set of security vulnerabilities (which if you read this
   list, and investigate, you'll notice that I do _all_ of the work to
   mitigate those issues).

b) doing this as you might expect will interfere with performance for _all_
   applications.

The developer working on tmux is working through the latter, and ignoring
the former.  Perhaps in a few years, after both aspects are resolved, he
might want to adapt some of that to ncurses.
