My patches has been optimisations so far, which means that it's reducing
the amount of rewinds rather than eliminating them. With a slow enough
computer (for Intel, the Atom comes to mind), or lots of other things to
do for that computer (such as viewing an 1080p file?), the rewind flood
thing can still happen.
What client are you using to connect to PulseAudio? For gstreamer based
clients, my gstreamer patch was first applied upstream, then reverted
for reasons I don't fully understand. Applying it is likely to help
against rewinds. See bug https://bugzilla.gnome.org/show_bug.cgi?id=641072
