Of course it is possible to implement it under Linux without requiring
privileges too, just not with the standard, unmodified LinuxThreads
package. There are several userspace threads packages available (I
think the GNAT runtime has its own too) that work in a single process
context and don't need root for anything. Of course they all don't
scale to multiple CPUs on SMP machines.
