I am trying to fork a program. However I seem to be experiencing some strange behavior. I found the following reference to the use of fork:

http://www.tutorialspoint.com/perl/perl_fork.htm

From where I copied the following code snippet: 

#!/usr/bin/perl

$pid = fork();
if( $pid == 0 ){
   print "This is child process\n";
   print "Chile process is existing\n";
   exit 0;
}
print "This is parent process and child ID is $pid\n";
print "Parent process is existing\n";
exit 0;

#This will produce following result

This is parent process and child ID is 16417
Parent process is existing
This is child process
Chile process is existing

The expected output is shown above and is what I expected from reading the definition of fork.

However my code ran and gave the following output: 

This is child process
Chile process is existing
This is parent process and child ID is 16417
Parent process is existing

[download]
In other words the reverse order. This is exactly the same behavior I have been experiencing.

I am running on Linux debian with perl 5.08.08

Any help would be much appreciated.
