I stand corrected: Not even
ps2pdf CatStevens-FatherAndSon.ps CatStevens-FatherAndSon.pdf
returns. It hangs as well, so my proposed solution would not work 
anyway. I switched to afpl-ghostscript and that it works fine now.

Still, what do we do if it hangs? Lilypond is supposed to be "robust". 
Can we protect outselves from hanging when a subcommand does?
