Most of the so-called "leaks" you see with top / ps aren't leaks, but
artefacts of GUILE, that thinks that it should adjust its footprint to
the supposedly high memory usage of LilyPond. The last time this
happened was when some bozo introduced the use of (ice-9 format) in
the backends.

To troubleshoot this, it would be helpful to know which commit
introduced the problem.

I confirm that devel branch lily memory usage increased a bit recently
on my x86 Fedora Core box, but there are certainly not as many or huge
leaks as there used to be.  I trust the hackers to fix them before
2.12 :-)

Anyway, it seems logical to a simple user like me that as LilyPond
automates more the engraving process, it uses more memory and CPU time.
