So I assume with UCLinux on a 68K, there's nothing to stop a rogue program from destabilizing the system? (Mind, not a hostile program, just a buggy program.)

So I assume with UCLinux on a 68K, there's nothing to stop a rogue program from destabilizing the system? (Mind, not a hostile program, just a buggy program.) On an 8086, you can get a modicum of protection by limiting your processes to the Tiny or Small memory model (thus a rogue 16 bit address can't easily "leak" out of their respective segments and clobber the kernel).
