Wrapper around the pcntl_fork() stuff, with a API set like Java language.
Practical usage is done by extending this class, and re-defining the run() method.
This way PHP developers can enclose logic into a class that extends PHP_Fork, then execute the start() method that forks a child process.
Communications with the forked process is ensured by using a Shared Memory Segment; by using a user-defined signal and this shared memory developers can access to child process methods that returns a serializable variable.

The shared variable space can be accessed with the tho methods:
o void setVariable($name, $value)
o mixed getVariable($name)

$name must be a valid PHP variable name;
$value must be a variable or a serializable object.
Resources (db connections, streams, etc.) cannot be serialized and so they're not correctly handled.

Only runs on *NIX systems, because Windows lacks of the needed pcntl ext.
