Description

With patches from: http://lists.freedesktop.org/archives/spice-devel/2015-May/019796.html

While copying big files from guest to client by putting those files in the shared folder, the sessions freezes. channel-webdav and spicevmc have a heavy workload repeating the following debug over and over again. (I've included a debug on phodav to check the amount of data requested each time, which is 8192 bytes). The sessions is normal once the file has been copied.

Client and Guest: f22 Using spicy with latests spice-gtk git with above patches applied.
