Response Starts here. Yep I been on a rant and need to study. Microsoft will say whatever they want. Do what they want. But, this reentrant kernel seems to be true. I just sent a long msg about some of this. In short, "he who moves the most bits the fastest and cheapest wins". That really is the bottom line. Heading back to FreeBSD.org now. -d Peter McGarvey wrote: > > I've just looked at the following: > > http://www.freebsd.org/releases/3.0R/notes.html > > and found the following: > > "The kernel is mostly non-reentrant as yet, but work is under way" > > So I would imagine FreeBSD's kernel is still non-reentrant. > > The only way to truly check is something is fully reentrant is to read the > sources.
