wxExecute hangs on intel based Mac

[eilers]

There is a real problem with intel based Mac's and the wxExecute
command.

(tested and reproduced with the current CVS version, compiled on a
MacBook Pro!)

If it used with wxEXEC_SYNC, it just hangs in the following while loop:

int wxGUIAppTraits::WaitForChild(wxExecuteData& execData)
{
[...]

while ( endProcData->pid != 0 )
{

[...]

}

[...]
}

It seems as if nobody is setting the pid to 0..

If it is used with wxEXEC_ASYNC like this:
wxExecute(command,wxEXEC_ASYNC,theMakeProcess);

The method "OnTerminate()" is never called.

It looks as if the internal process notifcations are failing!

Btw.: It does not matter whether I disable one processor of my dualcore
system!!

Is this bug still present in 2.9-svn on current OSX?

Tried to test this with exec sample on the latest TRUNK Cocoa build.

Running something either synchronously or a-synchronously does not produce a hanging.

However there is another problem:

1. Run the sample.

2. Go to "exec->Quit exec". Nothing happens.

Clicking on the red "X" closes the application.

(In [72945]) Use wxID_EXIT for the "Quit" item in the exec sample.

This fixes the behaviour of the standard "Quit" menu item under OS X.

See #3204.
