Which is good, since it helps to find leaks. (And IMHO it's a good
idea to run and/or build lilypond with limits tightened with ulimit,
not only for the number of processes but also for open files,
allocated memory etc. -- I found some nasty leaks in texinfo some
years ago)

If you've 32k processes running on an average machine, you're in
serious trouble -- and your machine isn't that average ;-)
