This reverts commit 00c6b1649d.
It's been reported (and I can confirm) that this change breaks
`process.title = 'foo'` in Node.js.
Since libuv just calls out to Core Services and Application Services,
and since those frameworks are really just black boxes that you can't
look inside, it's impossible to debug what exactly goes wrong. Revert
it is then.
