Review the following, in particular the section about AppKit (also
best to read the whole document)...

<http://developer.apple.com/documentation/Cocoa/Conceptual/Multithreading/ThreadSafetySummary/ThreadSafetySummary.html#//apple_ref/doc/uid/10000057i-CH12-SW1>

"You should create, destroy, resize, move, and perform other
operations on NSView objects only from the main thread of an
application."

You should only create view object graphs, etc. from the main thread.
Look at using -[NSObject
performSelectorOnMainThread:withObject:waitUntilDone:].
