That is indeed most likely the mode in which the gdb side of things has had
the most testing.  So starting with non-stop may open more gdb pain while
avoiding some pain in the kernel module.

Yes, that's fine.  For a starting place, having only reading support is OK.
These bits are relatively trivial to fill in later as needed, so I think
made plenty of sense for Oleg not to include them yet.
