[Qemu-devel] [PULL 28/31] curl: Remove unnecessary explicit calls to int


From: Kevin Wolf
Subject: [Qemu-devel] [PULL 28/31] curl: Remove unnecessary explicit calls to internal event handler
Date: Wed, 30 Apr 2014 20:24:00 +0200

From: Matthew Booth <address@hidden>

Remove calls to curl_multi_do where the relevant handles are already
registered to the event loop.

Ensure that we kick off socket handling with CURL_SOCKET_TIMEOUT after
adding a new handle.
