Before a process is replaced by os.exec*(), userspace buffers usually need to be flushed. However, it is not necessary to flush kernel buffers to disk using os.fsync(). Flushing userspace buffer to kernel, and flushing kernel buffer to disk, are two different things. In addition, os.fsync() is not applicable to pipes or sockets. This patch removes this confusing information.
