http.Agent: idle sockets throw unhandled ECONNRESET
Please see this code: https://gist.github.com/thorn0/0812cdb7eb12b2348337 That's what it outputs for me (Node 4.2.1 and 5.0.0, Windows 7 x64):
1.108s: Complete
121.193s: uncaughtException
Error: read ECONNRESET
at exports._errnoException (util.js:874:11)
at TCP.onread (net.js:544:26)
It's reproduced with most servers that run Microsoft IIS.
