Exactly. The real question is, how far the effects of this deadlock can spread. If it remains within control of the user that mounted the fuse filesystem, than that's okay. If it affects processes not controlled by the user, that's bad. So it's not about being able to stall a process that accesses the filesystem, that's trivially doable using fuse even without any page faults. I'ts about being able to stall an unrelated process.
