Does the same happen when the swapfile is on /mnt/us ?
I don't recall which of those FUSE layered file systems twobob used.

I do recall that twobob did his work via ssh over wifi.
(ssh, sftps, scp, vlc, etc)
The USB cable was just used for external power.

So it is possible that in his use-case he never had the opportunity to discover any inter-action with the exchanging of kernel driver modules and the swap storage.

But I do know that he ran native compiles on his K5 that where long running (libwebkit-gtk takes days) without troubles.

Some of the other people using swap - - -

Some created a file in USB storage, converted it to a device (with losetup) and then used the swap partition driver on that device.

Geekmaster used (or at least tested) doing swap over an NBD over WiFi connection to his pc.
I don't recall if he ever used (or even tested) NBD over the USB cable network.

One note on the NBD + network driver combination -
There is (or at least there was) a rather rare kernel deadlock path in that combination.
But it is (or was) rare and did not corrupt anything, just required a hard (power button) re-boot.
