Description:
------------
I've experienced this problem for years but have never bothered to report it until now.  I write a lot of command-line PHP scripts and I've found that scripts that do not attempt to open a socket connection terminate immediately at the end of the program.  However, scripts that contact remote (or even 'localhost') servers (i.e. open a socket during script execution) hang for about 5 seconds before returning control to the command prompt.  I only experience this issue on Windows machines.  Linux and OSX boxes seem unaffected.

Test script:
---------------
<?php
	file_get_contents("http://www.google.com/");
	echo "Hi!\n";
?>

Expected result:
----------------
Return to the command prompt as soon as the "Hi!" is output.

Actual result:
--------------
Reaches the end of the script (after displaying "Hi!") and simply hangs for 5 seconds or so.
