This would be the rough pseudocode (a very rudimentary one).
$SIG{ALRM} = sub { exec (self) };
alarm (2 mins);
do stuff;
There is a race between the alarm and do stuff. How it would affect your
program, you can judge better

wouldn't it be better to check ARGV to see if arguments have been passed. if so use
that as
input. else read on STDIN.

the correct way would be to form a small grammer and parse it. there is an article on
using Parse::RecDescent for parsing.
however this seems really trivial. you can handcode it easily.
for example something like

error handling can be designed after two streams of logic:

do the parsing only if the flag is set.

All of the experts you are talking about started out some time as clueless newbies

man nice. perl doesn't seem to have a nice function. so you might have to invoke
the nice system call. you could also take a look at setpriority (linux, *BSD, SYSV
should
support it too). using it you can alter the scheduling priority of a process, children.

dunno about the select module, but a normal call to select will block.
that is why in my other mail i had given you the option of blocking on
select in another thread/process

this is what i understand from your mail.
you need your main code to keep running, while servicing I/O from the netstat FH (or
for that
matter, any FH).
Michael has already suggested pre packaged options, that should be able to help you
out.
however if you want to roll out your own code ava
the code that i sent you should be able to do that.

Cobalt RaQ runs apache as root so that their front-end can run with root
perms. You could use cgiwrap for the same effect, i suppose. there is also
webmin, which runs with root priveleges. but webmin has its own httpd server
coded in perl (thereby reducing the chances of buffer overflows and such)
i dont think perl has a syslog function. you could pipe the message to
logger though. a better way would be invoke the system call syslog.

would help if you could post the kernel version, any other log messages that
you might think would be helpful. the version of apache etc. in my limited
knowledge perl scripts on their own cannot cause kernel panic, unless the
kernel had a bug which is accidentally being exposed by perl.
