Well, here's a situation I'm not sure how to handle with .call... say
I have something like this:
this._process.bind(this, credentials, listener).defer();
"this" object has a function called _process which I want to execute
after the current call stack completes
If I did something like setTimeout(_process, 0); I can get the defer
functionality, but the scope (what "this" means) will be the window,
not the original object, and window._process, as far as I know,
doesn't do anything but blow up.
The problem might be my logic, not just the syntax - is there a more
efficient, or simply a different way of doing this?

<div dir="ltr">This is simplified version of what Prototype does with it's bind() function:
<span style="font-family: courier new,monospace;"> Function.prototype.bind = function(scope){</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">   var _this = this;</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">   return function() {</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">     return _this.apply(scope);</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">   }</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;"> }</span>
So, this code below equivalent with yours
<span style="font-family: courier new,monospace;"> var _this = this;</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;"> setTimeout(function(){</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">   (function(){ this.process() }).apply(_this);</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;"> }, 0);</span>
This one even more simple:
<span style="font-family: courier new,monospace;"> var _this = this;</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;"> setTimeout(function(){ _this.process() }, 0);</span>
Do not use bind() in jQuery, take advantage of module pattern instead.
