One possible reason I can think of -
"- exiting this loop means all compared chars were identical hence it
is a palindrome and i return True"
is probably incorrect reasoning. Think again.
Also, you may consider posting your code in a way that preserves the

Even if you replace the python mbox code with something that uses
fcntl.flock() to protect against concurrent updating, you should also
understand that NFS does *not* provide full Unix filesystem semantics.
In particular, Unix flock(2) (which Python's fcntl.flock() wraps)
doesn't work over NFS.
