slackbuilds/libraries/libeatmydata

libeatmydata is a small LD_PRELOAD library designed to (transparently)
disable fsync (and friends, like open(O_SYNC)). This has two
side-effects: making software that writes data safely to disk a lot
quicker and making this software no longer crash safe.

DO NOT use libeatmydata on software where you care about what it
stores. It's called libEAT-MY-DATA for a reason.
