Summary: embedding on OS X Aqua is problematic

Initial Comment:
macosx/tkMacOSXInit.c's TkpInit function is not
friendly to applications that embed Tcl/Tk.

One bug is that it only works for the first Tcl
interpreter that an application creates -- this is not
a problem for the X11 and Windows versions of Tk.  The
symptom is that one's ported application crashes
mysteriously because Apple events refer to a Tcl
interpreter that no longer exists.

The next bug appears once the application is rewritten
to use only one Tcl interpreter (in my case, reuse the
Tcl interpreter from the splash screen for the main
part of the application).  Then an extremely helpful
console window appears (because the application was
started by double clicking and Tk thinks it was started
up via Wish.app) that is unwanted and unneeded.  (The
console appeared before, but quickly disappeared when
the first Tcl interpreter was destroyed.)  There is no
reasonable way to disable this behavoir without
modifying the Tk source code (I want to leave stdin
alone, thank you very much).
