spawn() beats fork()[;] fork() should be deprecated
Spawn is a further complication of exec, which tells what signals and
file descriptors to inherit in addition to what arguments and
environment variables to pass.
Fork has a place. For example, Program 1 in
www.cs.dartmouth.edu/~doug/sieve/sieve.pdf forks like crazy and never
execs. To use spawn, the program would have to be split in three (or
be passed a switch setting).
While you may dismiss Program 1 as merely a neat demo, the same idea
applies in parallelizing code for use in a multiprocessor world.
