Re: bugs to fix before 4.4.0 release

In addition to straightforward bugs, I'd like to see the performance not
degrade too much between releases.  I know that this is a trivial test, but
the performance of double-nested for loops shows that performance has been
declining over major releases, and that the development branch is 2.6X
slower than 4.2.1.

Sample Code:

a = 1; b = 1; t0=tic; for i=1:1000; for j=1:1000; a = a + b + 123.0; end;
end; t1=toc(t0); t1


3.8.2 : 0.84617
4.0.3 : 1.4062
4.2.1 : 1.43
4.4.0-dev : 3.77
