Linux has been booting on SMP boxes since 2.0.x. 2.2.x is where most of
the SMP performance work was done and it is still continuing in 2.3.x.

Tools: main missing pieces:

1. Debugger that can debug the pthreads implementation. Various patches
   exist, but the shipping versions lack support.
2. 1:1 user:kernel thread implementation - it is more of a matter of opinion.
3. Inability to handle a large number of runnable processes.

The ideal SMP application for Linux will use the multi process model and spend
a large amount of time in user mode.
