unique for a given dependence DAG.
Shells can be issued and completed at random order(only need
satisfying the dependence relation). But make can print their outputs

parallelism of CPU is transparent to programmer.
What I want is transparent "parallel make". Make can issue multiple
shells simultaneously, but print their outputs in the same order as in
a serial make.

The use of semaphore may impair performance.

Parallelly invoked shells(and commands the shells invoke) may print to

Sorry, I don't understand this.
You probably misunderstand the meaning of "serialization of output"
and "parallel make".

As parallel make are becoming more and more popular, can make
serialize the output of parallel make?
Make can redirect every parallelly issued shell's output to an
temporary file, and output the stored output serially, as if in a
serial make.
