When a new process is launched it ensures that all files under its uid/ and uid/pid hierarchy are accessible by the user/group of that process. If the directory already exists that means the access permissions have been already set before, therefore we do not need to reset them again. This also avoids a race between two processes in the same uid with one process being launched and walking the uid/ directory while the other process is being killed and changing the content of that directory. In such a race the process walking uid/ might find the uid/pid directory of the process being killed but by the time it tries to set its permissions the directory might be removed because the process got killed. The change eliminates the possibility of this race.
