Script being kept alive

[oscar-broman]

The script doesn't exit automatically like it should when waitpid has been used. Commenting out the line that waits causes the script to run for 1 second then quit, as expected. With waitpid, however, the script just keeps running.

var waitpid = require('waitpid');
var childProcess = require('child_process');

var child = childProcess.spawn('sh', ['-c', 'sleep 1']);

console.log('waiting..');
waitpid(child.pid);
console.log('done waiting');

Tested with Node.js v0.10.4 on OS X and v0.10.7 on Debian 6.

One way to fix this is changing the following line:

r = waitpid(child, &status, WNOHANG);

to this:

r = waitpid(child, &status, 0);

I'm not sure, though, what other features that breaks.
