A C Zoom

~/bin/timed-copy -v -m 80 blah.mpg
...will read using 524288 bytes buffer, for 80 minutes
...read 282.36, wrote 282.36 MBytes, took 8.42 minutes

So it looks like the alarm is fubar.

I fixed it as such...

while (1)
my $tn = time();
[...]
last if ( (($tn - $t1) / 60) > $minutes)
# last if ($timerExpired);
}

Yeah not as fancy as using signals and timers, but it works :)
