hlsdemux doesn't need to drain downstream demuxer/decoders before doing 
the switch, so it seems something else would be the issue.
Is this happening with every stream or just with some particular one? 
The buffering inside the pipeline should be enough to allow the switch 
without causing pauses, even if there is some overhead.

Does this happen both when switching to a better and to a lower resolution?
