Update Timer?

I am building a simple database using a tree and a ReferenceStream as learned here.  I want it to update the disk file every 10 min. with the current tree.  What should I do?

The classes Time, Duration, Stopwatch, Schedule, look like possibilities but the only method that looks good is Schedule "between: aStart and: anEnd do: aBlock" but I don't want it to hang waiting on the timer so the tree can't take my changes.  How do I make something perform like a text editor that saves its work every 10 min?

Thanks,

Sleeping on a problem helped in this case.

Time current minutes < timer minutes + 10

ifTrue: [^#waiting].

timer := Time current.

I put that in an update method called by methods that change the data.  Not guaranteed every 10 min depending on user behavior but close enough and easier than defining a process.
