Of course its not _always_ possible, but most of the time it is.

Can't answer that one.

In general using only 1 thread is better because you avoid all
concurrent-access problems you get when having multiple threads. You don't
need to make sure you're accessing data only from one thread at a time,
debugging is a lot easier, you avoid a lot of possible timing issues
because sometimes one thread runs "faster" than another and causes a
problem.
