* env (environment for the daemon) (default: process.env)
* cwd (current working directory for daemonized script) (default: process.cwd)

Example for passing file descriptors for stdout and stderr:
```javascript
var fs = require('fs'),
var stdoutFd = fs.openSync('output.log', 'a');
var stderrFd = fs.openSync('errors.log', 'a');
require('daemon')({
stdout: stdoutFd,
stderr: stderrFd
});
```

Daemon actually re-spawns the current application and runs it again. The only difference between the original and the fork is that the original will not execute past the `daemon()` call whereas the fork will.
