So, let it use a temporary file. What's the harm? An anonymous mmap
region is still mapped to the swap file. Might as well give it a name.

You know that this is not C, and that the parentheses are not needed in the
"if" statement? In my opinion, they interfere with readability.

es. The same kind of issue
occurs with mod_python and the multitude Python web frameworks, and many of
them detect changed files and automatically restart. If you really need a
clean environment, then you need a new interpreter.

I think you misunderstood. (B) is *ALWAYS* the proper way of doing
parameterized SQL queries. Unconditiona

What's the point? Why can't the actual user of the port create the port,
and then notify the other side of the port number?
And why don't you just specify a port number of 0 and let the system assign
you a free po
it were a directory. It's a very handy feature for distributing
premade packages.

Nevertheless, it IS the answer for many questions in the Python world.
That's the advantage of being Benevolent Dictator For Life.
