dirmngr goes berserk making tor requests after gpg --recv-key attempt ends

I'm not sure where we should actually file this ticket, but I'm going to start here so I can get my logs up somewhere before they disappear.

I run Debian, and have the single line "use-tor" in my ~/.gnupg/dirmngr.conf.

I unslept my laptop recently, and did a

torify gpg --recv-key ...

which hung. Eventually I ctrl-C'ed it.

Later, I realized that my Tor was working really hard to make connections. Here is a little snippet from 'setevents circ stream orconn'

These were just streaming by. You can tell from the streamid of 2400 that it had made many many streams already.

$ netstat -aen|grep 9050|wc -l
260

"lsof|grep 9050" told me it was dirmngr making the connections.

I kill -9'ed dirmngr and the stream requests stopped.

That can't have been good for the Tor network. Especially if we have even a small pile of people with this buggy berserk dirmngr hammering the network nonstop forever.

It seems like we might want to track down the poor decision making choices inside dirmngr, for the good of our network.
