Problem with json request handling causes audio/video drops

[josebiro]

JSON requests cause audio drops and video stutters while playing any video media, all file types and resolutions.

This problem effects the arm linux build before and up to beta3. Haven't tested other platforms.
hardware: pivos xios ds - ARMv7 amlogic meson-m1

Workaround for the problem is to disable programs making aggressive json requests - in my case it was the "Skin Widgets" service.

Sample log of an event that lead to a couple of audio drops in sequence:
