-connect to unreachable node seems to slow down wallet after a while #4034

I had a wallet connect to a node on "localhost" (ssh tunnel). The tunnelled node became unreachable and over time the wallet seemed to slow down. And by slowing down I mean I was getting time-outs on RPC requests over ssl.

I noticed the time outs were gone after restarting the wallet once, but gradually came back. Now that I restarted the wallet without the -connect to the unreachable node I have not had a time out since.

(version 0.9.-something)

Can you reliably reproduce this? I have a candidate fix.

@Joukehofman can you test if #4037 fixes this issue?

I talked with gmaxwell on IRC about this issue and it is not easy to reproduce I am afraid. But if I remember correctly we also came to the conclusion that this commit may not have corrected this issue. IRC-logs: http://bitcoinstats.com/irc/bitcoin-dev/logs/2014/04/09#l1397062552

Seems like either the issue is fixed or at least hasn't provoked any discussion for nearly 4 years, closing now...
