Qt4 seems to encourage sloppy (slow/memory intensive) coding for some
reason.  Also, Qt4 lacks many functions that Qt3 offered, leaving
programmers to try to re-implement them.  I have found that many of these
re-implementations are less efficient than the original internal Qt3 code
was, partially due to unexposed internal Qt variables.

Just my $0.02.
