Wonderfull!

Which version? There's a beta version of 1.1, the stable should be 
released on January 14th, as this is jquerys first birthday.

It should (!) return the XMLHttpRequest, so one can manually abort it 
(at least $.ajax() does so, I think, $.post is just an alias of a 
$.ajax() with certain parameters).

That's a perfect solution. I think a mentioned that before...

yes, the value should than be returned from inner function to the 
outmost function

With jquery you have the option of setting global ajax-parameters:
$.ajaxSetup( {setting:'value', foo:'bar', ...} );

if you pass in an object like the following, the JS will be halted while 
the post request remains unanswered:
var myAJAX_settings = {type:'POST', async:true};
