Seems to be fixed in CVS. (verify by trying the latest stable 
snapshot from http://snaps.php.net)

The following script:

<?php

echo "Hello!";
if (pcntl_fork()) {

   exit;

}

?>

Should produce only one "Hello!". The problem is that it appears to
restart execution of the script, causing the text "Hello!" to appear
twice.

This is _NOT_ how fork() works. The process should continue executing
from where the pcntl_fork() function call was issued, and exit the
parent process.

Is this related to SA_RESTART and changes made to restart signal
handlers in PHP 4.3.0?
