NSATSGlyphStorage memory usage.

Subject: NSATSGlyphStorage memory usage.
From: "email@hidden" <email@hidden>

My app repeatedly loads and unloads a couple of MB of text into an NSTextView.
Running heap(1) reveals

 heap 12462 -sumObjectFields | grep NSATS
 2  22833792 11416896.0   NSATSGlyphStorage   ObjC    AppKit

This 23MB memory is allocated in the auto zone and does not noticeably decrease if the NSTextView contents are small.

Would it be correct to assume these memory blocks are managed by the layout manager and will be reallocated as and when appropriate?

Regards
