processors hangs on sentences with long lists of numbers

[kwalcock]

I'm not yet sure where this happens. It may be that a rule includes a regular expression that can match too many ways. The program usually stalls for a long, long time and may eventually run out of memory and crash. Here are example "sentences":

It looks like it might be measurement-3 that is problematic. I see *)+. I think that Marco's algorithm doesn't backtrack, but it must keep tabs on all the possibilities, and maybe there are too many piling up.
