You're thinking very old-school.

What would be better than a timer is a set of configurable callbacks which
execute processing table segments upon various events.  

* Begin lookup
* Changed record
* End of matches
* Close lookup 

In this fashion, you can configure what you like, without having to rely
on an arbitrary timer which may be smaller than desirable, or larger than
necessary (thus wasting time).  Timers generally suck, to put it bluntly.
They're often too crude a tool.  Events are a much better methodology for
this sort of functionality.

And lo and behold, filePro already supports events in general terms.  So
why not have @brsbeg, @brsrcd, @brsend, and @brscls as system-based events
which function like conventional callbacks?
