At this point, a member of the audience asked about microkernel
architectures. Linus responded that this question has long since been
answered by reality: microkernels don't work. That architecture was seen
as an easy way to compartmentalize problems; Linus, too, originally
thought that it was a better way to go. But a monolithic kernel was
easier to implement back at the beginning, so that's what he did. Since
then, the flaw in microkernel architectures has become clear: the various
pieces have to communicate, and getting the communication right is a very
hard problem. A better way, he says, is to put everything you really need
into a single kernel, but to push everything possible into user space.
