Wonderful, thank you very much the hint, this did the trick.

So here it goes ...

(gdb) r test.ly

Let me know if there is anything else I could try or if I should
collect more "statistics".

This time the first lilypond run took 2,5 minutes to complete
(apparently I had additional problems with swap yesterday that
prolonged the process to almost 10 minutes).
