Comment #3 on issue 1618 by percival.music.ca: unpredictable placement of rests

I'm happy with this rationale.

Another note on valgrind: you _can_ use valgrind on lilypond, but in addition to all the memory errors it finds with guile (I'm not claiming that all these errors are *valid*, merely that valgrind reports errors), it also finds tons of uninitalized variables in guile. If guile was really _that_ full of uninitalized variables, then I can't see how it works at all... but guile clearly _does_ work, so I suspect that valgrind simply doesn't understand how guile sets up variables internally, and thus it's not useful.

Adding suppression files (for example, generating a suppression file from running lilypond with no arguments or files, then using that suppression file when generating the example in question) doesn't help. I only see a few instances of uninitalized variables, but these are all buried deep in the guile library.
