I use gpg with pinentry-gtk2.  When trying to sign or decrypt, if the
passphrase is not cached, the dialog pops up, and then when it's done,
the operation proceeds.  Then future operations succeed until the cache
expires.

It's true that when the window pops up interrupting emacs doesn't make
the window go away.  What happens is that emacs ran gpg which sent a
query to the gpg-agent process, which popped up the window.  So you
could argue that gpg should withdraw the request when killed, and that
this is a gpg bug.  But I don't think there's anything wrong with gnus.
