Comment (by lkarsten):

 This is most likely related to there being no sighup handler defined.

 Following patch removes the behavior for me:

 Downside is that we don't clean up what curses has done, so the terminal
 becomes garbled if it still exists. ("reset" fixes, of course)

 Same sitation on varnishtop.
