Not using random at all but using the pid, in contrast, should be collision-proof, assuming that we are not working on a shared file system accessed by multiple computers with separate process id pools. But then locking is likely to be non-working anyway.
The async I/O approach that I'd like to introduce in lilypond-book if I manage to should fix the collision risk.
