programs that use the filesystem from a realtime audio thread are
incorrectly written.
a system that allows disk i/o to interfere with a realtime audio
thread is badly configured.

ergo, i would conclude that the only realtime audio programs that can
benefit from this sort of thing are either badly written or running on
a misconfigured system.

JACK itself isn't doing any file I/O - it just happens to use an
inter-process communication system that uses identifiers that are
related to the filesystem.
