Root causing stack corruption post redoxfs mount
Context switching as a result of a read on a Packet socket in the loop at:
cookbook/recipes/redoxfs/source/src/mount/redox/mod.rs : fn mount
.. brings in a Context with an unmapped kernel stack which then bombs out when making stack references. I assume that kernel stacks are unmapped when a Context is SYS_KILL'ed but I can't see any relevant bits in the syscall trace.
