From d401ecbd70e02ad5b0cd7ab103359a23c6af3224 Mon Sep 17 00:00:00 2001 From: Linus Nordberg Date: Mon, 18 Nov 2013 15:30:00 +0100 Subject: Disable/delete events in the timeout callback. Without this, the sequence (1) send (successfully) (2) receive (timeout) (3) resend (successfully) will have the read event from (2) trigger a read in (3) and the response is lost.
