Sorry, but no.
You have this backwards. If you are going to be making suggestions, you
should be educating yourself and speaking from knowledge rather than
suggesting that problems are "easy" and then asking someone to prove why
they are not.
It is by no means impossible to implement the POSIX spawn functions but
implementing them fully would require quite a bit of work and you'd still
run into Windows limitations. You can either take my word for it or
study the subject yourself. I'm not going to educate you.
The particular code that you probably would want to study is in fork.cc
and spawn.cc.
