Summary: Accented characters not appearing where they ought to

Initial Comment:
Hi,
please read this forum thread for more detailed 
information :
http://amsn.sourceforge.net/forums/viewtopic.php?t=1164

I will summarize it here : 
It seems that on Linux, when an application is 
'frozen', by taking 100% cpu on some script, the 
keyboard events on a text widget make all characters 
that need the use of a deadkey appear as the last chars 
in the widget and they will all be the same as the last 
accented char entered.
Quoting from the forum : a message like "¿Cómo estás?" 
would appear as "¿Cmo ests?áá".
To test it, simply type in a wish shell :
destroy .t 
pack [text .t] 
after 5000 { 
   for { set i 0 } { $i < 100000 } { incr i } { puts 
test } 
}

The loop limit depends on how long you want it to hang, 
use the 5sec grace time to set focus on the text widget 
and while it's hanging, type a sequence of normal chars 
interleaved with accented chars (using a deadkey). See 
the result.
I was unable to reproduce it on Windows, but it was 
reported many times already and it is known to happen 
on Linux (FC5) with Tcl/Tk 8.4.12. I have no means to 
test it further. 
I hope it helps.
Thanks.

As you can see from the forum thread this bug originated 
from, it also happens with the latest CVS version of Tcl/TK 
(july 2006).
I don't know if you would prefer the group to change from 
8.4.13 to 8.5a4 or not.. as it happens in both of them. I 
just changed it, but I'd still like to see the fix retrofit 
in 8.4 if possible.
Thanks,

It was tested on the current stable (8.4.13) and it seems to 
reproduce again... I hope the user experiencing this issue 
will test it with 8.5 too.
How about the Tcl/Tk team, any feedback you can give me on 
this issue ?
