Thank you both for your replies. You are both quite correct and upon
testing I get the desired results. I was mistakenly expecting the
execution of the function to block at the fcntl.flock(f,fcntl.LOCK_EX)
line.
But I am slowly getting my head around it.
Thanks

The file you open() may be closed as soon as it is no longer possible to refer
to it.
So in the first case, because the top-level variable 'f' continues to refer to
the opened
file, the file may not be closed.
In the second case, no variable refers to the opened file after lock() returns,
so P
The following code works as expected when run in the main body of a
python script (ver 2.3.5) on OpenBSD v3.8. but when it is in the body
of a function definition it does not work. It does not raise any errors
but it simply does not block as expected. I have repeated this in both
a cgi envirnoment
