You are probably right, but it is hard to find such a test case,
because there is only one significant daily regression (I guess from merging),
but this one doesn't explain the overall change.
IMHO the graphs suggest that the daily bugfixes increased the compilation time
day after day. So, it's maybe difficult to clearly show which algorithms are
responsible for this regression.
Soever, I will search for some tests which will demonstarte this compile-time-hog.
