ENH: change system calls to fork/exec and CreateProcess

[EmosewaMC]

Is your feature request related to a problem?

This would allow for more control over security, less work being done by master and better heartbeat controls for detecting if a server is alive or dead.

Describe the solution you'd like

Replace calls to system with fork/exec on *nix and CreateProcess on Windows.

Repository breaking implications

Could prevent servers from starting on platforms without those commands.

Describe alternatives you've considered

continuing to use system and being complacent

Do you have a sample of the code you have in mind to be changed? I'm wondering if there's a C++ or POSIX API that might have more cross-platform compatibility.

There is no standard way of doing this. It will differ based on platform
