Isn't a write to a file that's opened as append atomic in most operating
systems? At least in modern Unix systems. man open(2) should give more
information about this.
Like:
f = file("filename", "a")
f.write(line)
f.flush()
if line fits into the stdio buffer. Otherwise os.write can be used.
As this depends on the OS support for append, it is not portable. But
neither is locking. And I am not sure if it works for NFS-mounted files.
