Unless there is a reason to do otherwise, use 0.  1 or 2 will adversely
affect the performance of the job changing the user space.

You would only use 1 or 2 if you need to ensure that the user space has the
last changes if the whole system were to crash.

In most cases user spaces are used for the output from a list API and if
there is any kind of a problem you are just going to start the whole process
over.  If that's what you are doing, definitely use 0.
