Really painful bug in 3.9

Hi folks,

Normally I work in 3.7, but recently I've been working on getting OB
up to snuff in 3.9. It's no fun.

It seems that slow drawing problem is still around in 3.9 and worse
than ever. In the good old days, you could watch each window being
redrawn in turn, and you could see text being drawn character by
character. Thanks to the radial gradients in 3.9's SystemWindows,
you now get to watch every window redraw EACH PIXEL of the gradient
as well. Opening and closing debuggers can take minutes if you've got
a lot of windows open.

This problem has been around for at least a year, and has been
discussed several times. See, for example:

http://lists.squeakfoundation.org/pipermail/squeak-dev/2006-January/
099650.html

Fixing this is beyond my ken, so I can only appeal to the gurus out
there: please, don't let 3.9 ship with this bug.

This is strange because this problem was fixed by adrian and marcus.
Marcus just told me that he never saw that behavior after the bug fix
was in.
On which platform are you? VM?

Mac/PPC, using both "unix 3.9-7" and "carbon 3.8.12beta4U" VMs. This
was with update 7038.

However, I just tried to trigger the problem in 7043, just to be
sure, and I couldn't. I may have a broken image, somehow. The 7043
image is much, much nicer.

The way to find out is to open a ProcessBrowser and see if there are
multiple UI processes running. If so, just kill one.
