Hole 1 (18, or 16 if I can take a free drop on pop)
sub {(pop=~/\w+/g)[4]}
Hole 2 (24 in tcsh)
perl -e'\ \ \ goto\ TPC'
Which has been said before, to be sure.
Hole 3 (20)
sub {pop=~/^(.+?)\1+$/;$1}
which takes a 1-stroke penalty for the lack of /s, and one for $ instead of \Z. Oh well.
Hole 4 (19)
sub {split//,pack"H*",@_}
or
sub {map{chr hex}pop=~/../g}
for one more stroke and a warmer fuzzier feeling (since I actually got that one done in the time limit).
Hole 5 (30)
sub {$a=pop;for(@_){$a>$_ or$a=$_}$a}
I think this is optimal for Perl 5.004 (tilly can do it better with a more recent revision, I know.)
Hole 6 (44)
sub {sub F{pop=~/[aeiou]/;$&}sort{F($a)cmp F$b}@_}
Which is not as cool as some, but is the best I could do without reading the thread.
This gives me an overall score of 155 for six holes, which I think is respectable...

    [oiskuu]: The useful bits that relate to your process can be found under /proc/self. What information are you thinking of? Tty name?
    [tye]: I just daemonized and getlogin() still knew who I had been.
    [tye]: perhaps loginuid ? Not that I concede that something not being in /proc means it is not useful.
    [Corion]: tye: That's really interesting, but maybe it is because getlogin() returns the name, or the uid, so if that user has been replaced by another user with the same uid in the meantime, that's no problem to the system...
    [davido]: or on ubuntu /var/run/utmp
    [Corion]: Otherwise, I would imagine that a user with a process still alive would lock that information in memory.
    [davido]: so last -f /var/run/utmp on ubuntu provides similar (though more verbose) info
    [oiskuu]: glibc getlogin just does ttyname() and falls back on getutline(); it's not security related at all. (reminds me of sendmail and remote finger services of the naive early spam era)
    [Corion]: But yes, "who started this process" is interesting information :)
    [tye]: no, I really believe that "login user" was added as a fundamental bit of info about each process in order to enhance the usefulness of auditing
