It looks like most of the calls are coming from [NSArray
indexOfObjectIdenticalTo:], half of which are from [NSSubTextStorage
release] and [NSTextStorage removeLayoutManager:]. I'm not exactly
sure why, as I didn't think I was directly touching the layout
manager.. is it being re-created every time I update the string or
something?

I'm trying to use an NSTextView to display the output of a shell

the order of a dozen lines nearly simultaneously), my app gives up
with a pinwheel. I'm using an NSPipe to get the data,
readInBackgroundAndNotify to know when to put it in my view, and
[[[myTextView] textStorage] appendAttributedString:] to do the
actual view updating. After a while, when my view starts to contain
thousands of lines or so, attempting to do any scrolling causes a
pinwheel for some length of time. Any ideas on how I could do this
better?
Have you tried using Shark or Spin Control to find out why this is
happening?
