That won't work for a variety of reasons. For one thing, the kernel is not going to like demand paging (COW, zero-fill, regular page faults) in the context of the kernel. For another, the kernel stack is of finite size and can't deal with typical programs. Using the user's stack is "a major problem" in it's own right. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
