Sorry if this is a bit off the normal topic but I'd really like to be
clear on this. Linux has only user mode threads currently, right? Is
someone is working on kernel mode threads, and if so, does anyone know
the status? Also I thought Solaris had kernel mode threads? The first
sentence above seems to say otherwise?
