One X multitasking "timeout"

So one of the many intensely annoying things about the One X - and not just because it has Sense - is this habit of it chopping tasks prematurely. It's particularly noticeable on audio apps.

Now it's possible that it's doing it for battery reasons - and I realise it's a Sense thing probably - and indeed, in comparison to my other phones the One X runs down like a cat that's had a grenade go off behind it on a flight of stairs. However it's functionally debilitating. Is there a way to mitigate this behaviour?

If relevant, I buy all my phones SIM-free so it's an international factory unlocked model. I've installed all the pushed updates thus far.
