OK, that sounds like a plan, yes.

"Really soon now".  Within days, I'd say.  There are some open Xmega
issues which I'd like to reproduce/fix, but then, with the many
bugfixes that came in, I think a new release would be due.

That's already done right now, in order to call the teardown handler
of each programmer.

Exactly, and performing a synchronous exit() from within a signal
handler wouldn't do very well, as it would just extend the requirement
to not use things like malloc/free into the atexit handlers (where the
currently existing teardown handlers are all doing some memory
management).
