Unfortunately, I was wrong. Performance hit is around 10%: 6885 seconds
CPU time against 6106 seconds. Timing may be not very precise as I used
the box during regression runs, but the main picture is clear.
In addition, there is some subtle bug that causes node counters differences
on some test files. I was unable to track it down.
So, the question is: should I abandon this project? I myself is uncertain.
10% or even more seems like somewhat too high a price.
