I don't understand. Closing a file descriptor that isn't open is
harmless, isn't it? Closing one that _is_ open only affects the
current process. If ot

They can be tiny because libguile-2.0.so, the interpreter, is a dynamic
library and is installed on the computer. It's barely different from how
compiled C programs can be a few kilobytes in size because libc.so is
dynamic.

Let's suppose somebody passes me a file descriptor to work with. It could
come from somewhere else, but for the sake of discussion let's pretend I
create it myself this way:
import os
fd = os.open("some path", "w")
I then turn it into a file object:
file_obj = os.fdopen(fd, mode)

I assume the answer is "Yes", but is it safe to expect that
tempfile.mkstemp() will only create a file that doesn't already exist? I
presume that there's no chance of it over-writing an existing file (say,
due to a race-condition).
