Given the stern warning on the php page about pcntl, and since php is  
almost always used in a webserver environment, I'd think it would be  
best to make this an optional variant, which must be explicitly  
enabled (+pcntl), rather than one which must be disabled as some  
others have suggested (+disable_pcntl).

http://us3.php.net/pcntl:

Process Control support in PHP implements the Unix style of process  
creation, program execution, signal handling and process termination.  
Process Control should not be enabled within a webserver environment  
and unexpected results may happen if any Process Control functions  
are used within a webserver environment.
