In my app, I call AXUIElementCopyAttributeNames() and AXUIElementCopyAttributeValue() very frequently, but as far as I can see, the resulting objects are all properly released and ObjectAlloc and MallocDebug show no indication of possible leaks

In your code, do you call CFRelease() on the attribute names and the attribute value when you are finished with them? The convention for Core Foundation functions like these is that, if the function contains the word "copy," you are responsible for CFReleasing the object. This applies to the accessibility functions.
