Threading is the way parallelism can be achieved using a "standard"
programming language and running the result as a "standard" program on a
"standard" OS with "standard" computer hardware.
Of course there are lots of other options such as Multiple Data CPU
instructions, starting multiple programs. and even using FPGAs (to be
programmed in languages like "VHDL" (where parallelism is the "simple"
syntax, while sequential execution needs do be dedicatedly coded).
The only thing that seems to be a viable option for a future "normal" PC
compiler could be stuff like "parallel loops" (appropriate Pascal syntax
is already done in Oxygene), as a syntax candy on a library allowing for
parallelism by using a thread pool.
