Before, doing this:

    var sys = require("sys");

    var obj = {
      one: 1,
      two: 2,
      three: {
        value: 3
      }
    };

    sys.p(process.mixin(true, {}, obj));

Would output this:

    {
     "two": 2,
     "three": {
      "one": 1,
      "two": 2,
      "three": {
       "value": 3
      },
      "value": 3
     },
     "one": 1
    }

When it should have outputed this:

    {
     "one": 1,
     "two": 2,
     "three": {
      "value": 3
     }
    }

Doesn't work on Linux.

This reverts commit 05d6da6c.

Run a max priority ev_timer every 2 seconds. If there aren't any pending
watchers then call V8::IdleNotification() once. This is slower at freeing
memory, but I think simpler and less aggressive.

The module loading code is looking extremely messy. It needs a refactor.

I don't want users to have to think about coroutine safety.

This is to reduce our dependency on wait(). For some reason this patch
affects the timer test:

  % ./node test/mjsunit/test-timers.js
  diff: 989
  diff: 989
  diff: 1989
  diff: 2989

Previously it showed:

  % ./node test/mjsunit/test-timers.js
  diff: 1000
  diff: 1000
  diff: 2000
  diff: 3000

I'm not sure what caused this change, and it's rather disturbing. However I
want to remove wait() as soon as possible and so am pushing this patch
through.

The module loading code is becoming increasingly ugly - this patch has not
helped. A refactor needs to be done soon.

I hope I won't spend all my time now maintaining this file...
