Thanks, everyone. Looks like the approach is to determine how
long I'm willing to wait, then count down from there. I especially
like John's example of using "time".

You can use sleep to pause and then use a counter to pause for a max
number of seconds.
my $max='500';
my $time=0;
unless ((&shlock("$somedir/.cache.LOCK")) or ($time==$max)) {
print "$main'program_name: cache already running\n" if $verbose;
sleep 5;
$time+=5;

unless (&shlock("$somedir/.cache.LOCK")) {
print "$main'program_name: cache already running\n" if $verbose;
exit;
