Linux provides the setrlimit() system call for this purpose -- you could either call it as a wrapper around lilypond, or hack it into a de-fanged version of Lilypond.
If you're going to be running an auxiliary rendering process or special-use server anyway, a few moments Googling finds the "softlimit" program, provided as part of the daemontools package, which looks like it is intended for providing the sort of limited sandboxing required here.

We already have several ulimit.sh inside phase3/bin for that. If LilyPond extension were using wfShellExec instead of exec, it would be automatically limited by $wgMaxShellTime, $wgMaxShellMemory and $wgMaxShellFileSize (unless on Windows).
Does that even work? I've regularly had issues with convert commands that can't get enough mem to finish and are never killed so they sit in the process list hoarding it.
