      This is peculiar:

      ~/main $ ./mongo
MongoDB shell version: 2.3.1-pre-
connecting to: test
> t = db.b
test.b
> t.insert({x:102})
> x = t.findOne()
{ "_id" : ObjectId("50dc0ce9f5c263c5c9f56781"), "x" : 102 }
> x.pack = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
> 
> t.save(x)
> 
> t.find()
{ "_id" : ObjectId("50dc0ce9f5c263c5c9f56781"), "x" : 102, "pack" : "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" }
> 
> x
{
	"_id" : ObjectId("50dc0ce9f5c263c5c9f56781"),
	"x" : 102,
	"pack" : "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
}
> delete x.pack
true
> 
> x
{ "_id" : ObjectId("50dc0ce9f5c263c5c9f56781"), "x" : 102 }
> 
> t.save(x)
> 
> t.find()
{ "_id" : ObjectId("50dc0ce9f5c263c5c9f56781"), "x" : 102, "pack" : null }
>

      as one would expect the field pack to have completely gone away.
