While browsing through the source of pm-utils, I noticed that the
lock/unlocking functions were using file creation/removal and PID
checking for locking purposes. In a shell scripting language,
however, there is no way to atomically create files.
Directory creation, however, is atomic. Here is a patch to atomicize
the lock/unlick functions.
