The results are better but still 7.5 times slower the apr 1.4 :(

Apr 1.4 	takes 2 minutes
Trunk r758624	takes 15 minutes to finish

Didn't do memory profiling, but it looks to me that memory usage
is much higher.
With apr 1.4 the test program shows the constant 3.6MB memory usage.
With trunk it cycles from 4.4 to 9.6 MB.

One pragmatic question.
What was wrong with the good old implementation?
