You don’t see that as a filesystem integrity problem?

Have you noticed that, on modern Linux systems, fsck invocations don’t need to happen that often? Yet your proposal would require them to happen much more frequently, even without abnormal shutdowns? Namely, you now have to have them as a regular part of normal system operation?

In other words, do you realize you are requiring a filesystem garbage collector? Do you know that it is bad enough running them on RAM (as required by languages like Java and Lisp), running them on much slower persistent storage (even SSDs, never mind disks) would cause an unacceptable impact on performance?
