Temporary file management in Perl -- is it possible?

[taint]

Greetings, I'm trying to discover if I can give a temporary file a "Life Span"
in Perl. Is such a thing even possible? My sutuation:
I'm generating a symlink (perlfunc=>symlink) that prefaces a semi-random
number to the $filehandle, thusly:

#!/usr/bin/perl -wT
# testing with a web browser
print "Content-type: text/html\n\n";
use strict;
use POSIX qw(strftime);

my $gmtstring = strftime "%H-%I-%S", localtime;
my $filehandle = "relative/path/to/filename";
my $dir = "."
if (-r $filehandle) {
    $filehandle = "readable";
}else{
    $filehandle = "unreadable";
}
if (-w $dir) {
    $dir = "writable";
}else{
    $dir = "unwritable";
}
unless ($filehandle && $dir) {
symlink("$filehandle", "$gmtstring-$filehandle")
}else{
    print "$filehandle<br />$dir";
}

This much returns the anticipated/expected results. However,
I want the newly created symlink to "vanish" (perlfunc=>unlink)
after --say, a 10 minute period. Is there ANY way to tell Perl to unlink
the symlink -- like creating a timer, or something? I'm not sure where to go with
this. I could create a cronjob. But I would really rather keep
this "self-contained" if it's even remotely possible.

Thank you for all your time, and consideration.

UPDATE It also occurred to me that a session || sessions, might also be a solution.
In the "big picture" these "temporary" symlink(s), are largish files of complete systems for
embedded systems. I only want them to become available for those that actually want to use them --
not to embellish other ppl's web pages, and for "bots" to suck down ~50 times/day. So
it occurs to me that the "Life Span" of the file could be tied to a session.
Is that possible, or a better approach?

Thanks again.
