Details:

This is a weird one, but the first pause after an asynchronous system call is
ignored. Other system calls are fine.
Simple example:

disp('should pause 1 sec each time...')
pause(1)   % is done
system('ls'); 1
pause(1)   % is done
system('ls',0,'async'); 2
pause(1)   % this one skipped
pause(1)   % this one is done
system('ls'); 3
pause(1)   % is done
disp('done')

Takes 4 sec rather than the desired 5.
