Rotated NSImage drawAtPoint:... slow

I just finished working on a view that draws some stuff at an angle 
including an NSImage created from a tiff with alpha.  It worked great 
in the test project with no noticeable performance issues.  I 
imported it into my main project and hooked it into my view hierarchy 
and it now hangs for about 8 seconds while loading the view.  Looking 
at samples all the time is being spent in -[NSBitmapImageRep 
loadData] for that image (its only 138x188px).  If I comment out the 
drawAtPoint: call that draws the image the view loads without any 
hang time.  Any thoughts on why this would be happening?  This is on 
10.4.11.
