If the temp directory gets deleted that means any temp files are also
gone. That's already a problem, e.g., when running a ":make" that takes
a while. Creating the directory anew just lessens the problem.
There must be no cron jobs that delete temp files, that is a
configuration error. On FreeBSD the temp files are not even deleted on
reboot.
The check if the directory exists takes a bit of extra time.
If we really want to re-create the directory, it's better done when
something fails, to avoid this extra overhead that is unecessary in
99.99% of the cases.
