Bug or feature? NSApp runModalSession

[Marko Riedel]

Hi folks,

I am using Apple's Cocoa documentation, which says this about
NSApplication's runModalSession:

Runs a modal session represented by session, as defined in a previous
invocation of beginModalSessionForWindow:. A loop using this method is
similar to a modal event loop run with runModalForWindow:, except with
this method the application can continue processing between method
invocations. When you invoke this method, events for the NSWindow of
this session are dispatched as normal. This method returns when there
are no more events. You must invoke this method frequently enough that
the window remains responsive to events.

The GNUstep implementation is different: IT DOES NOT RETURN
IMMEDIATELY when there are no events for the window. It waits
instead. The only way I can get it to return is to generate a few
MouseMoved-Events by moving the mouse.

I have noticed that GNUmail has code that uses runModalSession to
display a wait panel, which is sort of what I am trying to do. The
code is commented out, however. Does this mean runModalSession is not
working?

I could write my own event loop but I would rather not re-invent the
wheel.

This is my setup:
