------------------ Additional Follow-up Comments ----------------------------
I did look into the problem with the help of our test application and the 
retain count seems to come mostly from the NIB loading itself. Here 
intermediate objects get generated that never get freed again and thereby 
retain references to the window controller, as can be seen from this backtrace:

#0  0x08048fa2 in _i_MyWindowController__retain ()
#1  0x400abd92 in _i_NSNibConnector__setDestination_ ()
   from /usr/GNUstep/System/Library/Libraries/libgnustep-gui.so.0
#2  0x401e296d in _i_GSNibContainer__awakeWithContext_ ()
   from /usr/GNUstep/System/Library/Libraries/libgnustep-gui.so.0
#3  0x400ac910 in 
_c_NSBundle_NSBundleAdditions_loadNibFile_externalNameTable_withZone_ () from 
/usr/GNUstep/System/Library/Libraries/libgnustep-gui.so.0

I hope Gregory has an idea to resolve this problem.

Summary:  High NSWindowController retain counts

Original Submission:  When using a subclass of NSWindowController and a Gorm 
file, the NSWindowController doesn't get released when the window is closed, 
because the retain count is too high. There is a test for this here:

It should work on either gnustep or a mac with gnustep-make installed.
