greetings, monks! i need to make delays in program flow
using sleep $timeout; or select undef, undef, undef, $timeout; leads to the unexpected result: 
print "hello,\n";
sleep 2;
print "world!\n";
sleep 2;
print "bye!";

[download]
the result is: 
#hello,   - instantly
#after 4 seconds delay:
#world!
#bye!

really i need a "beeper" with delays: 
#some kind of cycle:
  {print "\a";
   sleep $timeout;
  }
