spawnProcess: Exit parent process without terminating child process

[timvol via Digitalmars-d-learn]

Hi guys,

I want execute a process. I know, I can execute a process using 
"spawnProcess" or "executeShell". But I want exit the parent.

My code for testing purposes is the following:

int main(string[] asArgs_p)
{
    if ( (asArgs_p.length >= 2) && asArgs_p[1].isDir() )
    {
        while(1) {}
    }
    else
    {
        import std.process;
        spawnProcess([asArgs_p[0], "test"]);
    }
    return 0;
}

So, starting the application without any parameter, it calls 
"spawnProcess" with an parameter. Now, I want that the parent 
process (the process started without parameter) terminates, while 
the created process remains running.

At the moment, the parent process creates the child and remains 
open (because of the while(1)-loop).

Any ideas how I can exit the parent and keep the child process 
running?
