Does performSelectorOnMainThread: preserve order?

Hi,

The GNUstep documentation for the
NSObject(NSMainThreadPerformAdditions) category states the following
for performSelectorOnMainThread: withObject: waitUntilDone: modes:

"Where this method has been called more than once before the runloop
of the main thread runs in the required mode [i.e., with
waitUntilDone:NO], the order in which the operations in the main
thread is done is the same as that in which they were added using this
method."
[additions mine]

However, there is no equivalent promise in Apple's documentation for
NSObject; it is conspicuous in its absence. Can anyone confirm or deny
that it has the same behaviour as in GNUstep?

(This question was previously asked on this list in 2006
(http://lists.apple.com/archives/cocoa-dev/2006/Feb/msg01215.html),
but I can find no answer to it in the archives.)

Thanks,
Hamish
