On windows there is no need to check the pid because KLockFile does not 
save pid's into the lockfile. If a file is locked by a process, 
KLockFile detects this case on file open - if the lockfile could be 
openend the process who created the lockfile has been died and the 
lockfile could be reused - see the comments in klockfile_win.cpp
