I thought about using ulimit, but it does not scale. In the scenario that the 
app has to support, client applications could create hundreds of thousands of 
unique properties, which would result in this many indexable fields.

Based on previous answers, the way out of this problem while still being 
scalable would be to use 2.1 where there is only 1 norm file.

However, it does not look like upgrading is an option, so I wonder if my 
current approach of mapping a property that a client app creates to one field 
name is workable at all. Maybe I have to introduce some sort of mapping of 
client properties to a fixed number of indexable fields.

...or modify the 1.4.3 code myself to get rid of norm files.
