Well, it doesn't loop.

Look at the attached two files:

The first file has 74 bars of a single voice, and `time' shows me the
following for processing it:

  real    0m52.985s
  user    0m52.707s
  sys     0m0.188s

The other one is the same as the first file but has only 37 bars

  real    0m4.447s
  user    0m4.332s
  sys     0m0.104s

It seems that we have some very bad exponential behaviour in
processing somewhere...

Conclusion: I was too impatient.  I should have waited a few days
until lilypond will have completed the chaconne.  My suggestion is to
send a copy of the current lilypond executable to the ASLSP project:
