To go further afield, this method (or using IO::File->new_tmpfile()
which is another interface to the same thing) is better because it, in
theory, produces non-predictable filenames. This is pretty crucial for
security purposes. The "in theory" part is in my statement because not
all operating systems produce good random names.  For example, SunOS
4.x has a lousy implementation of tmpfile.

If you want to be even spiffier in this regard, later version of Perl
(the 5.7.0 track) will be shipping with File::Temp which attempts to
do the "right thing" even when the operating system does not.

For more information on File::Temp and temporary files, see:


Hope this diversion is helpful to the RT developers and other folks.
