CursorLoader and my loaders *use* AsyncTask under the covers. Hence,
time ("take less than x mins") is not a particularly useful metric
here -- the behavior using Loaders or using AsyncTask directly should
be roughly equivalent.
If you like the Loader framework, use it, particularly if you are also
using a ContentProvider.
If you do not like the Loader framework, don't use it. Unlike, say,
trying to avoid EditText, the use of Loaders is purely optional. In
particular:
-- you can't use Loaders on API Level 10 and below unless you are also
inheriting from FragmentActivity
-- you can only use Loaders from an Activity, not a Service, at least at present
In those cases, your hands are tied: you have to avoid Loaders.
