That's generally tunable to taste using /proc/sys/* interfaces, and I suppose we also happen to have the full source code if we care to get fancier.

Plus, I have a feeling the player issues a swapoff() during startup anyway, in case a previous synchronise died and left it enabled.

That's easy enough to intercept. smile

Does the player normally try to enable swap during a sync?
Note that swapon -a uses /etc/fstab for the "-a" part, and if swap partitions are not listed there, it has no effect.

swapoff -a should work regardless, though.
