Unlockupd works around a bug in lookupd, a system service which is
required for proper operation of Mac OS X. If lookupd fails, the system
quickly becomes unusable. Unlockupd periodically checks lookupd’s status
and forces it to restart should it fail.
If you’re afflicted by the recently-publicized
lookupd system-wide freezes, this should serve as a temporary fix until Apple truly fixes the bug. It’s easy to install, and easy to uninstall. (Via MDJ 2005.09.23.)
