If one program opens file(in our case log file) and this file is moved or removed by other program, the first program still works with opened file descriptor. If we use WatchedFileHandler it allows to recreate file only after first emitting of WatchedFileHandler. It means that deleted files still consumes disk space. Class FastWatchedFileHandler is designed to observe file system. If log file is moved or removed FastWatchedFileHandler instantaneously closes old file descriptor and creates new file with specified name. Config option watch-log-file was added. If this option is set FastWatchedFileHandler handler will be used. Option watch-log-file brings effect for Linux platform only.
