If i use the "intel hyperthreading technologie", my
python application make a coredump with the output:

  File "C:\PROGRA~2\PYTHON~2\lib\lib-tk\Tkinter.py",
line 472, in after
    return self.tk.call('after', ms, name)
TclError: expected integer but got "9118984callit"

The test runs at the following system.
Microsoft windows 2000 5.00.2195 Service Pack 4
Intel Pentium 4 CPU 2.5 Ghz
522.988 KB RAM.


The error never occur, if i turn the hyperthreading in
the bios off.
I made the self test at 2 other pc with the same
hardware and configurations.  The result was the same.

I made another test with a linux pc, a laptop with xp
and a laptop with win2000. All without hyperthreading.
The error has not occured.

I add the log file and the test as attachment.

I believe TclError means that the error came from the 
embedded Tcl interpreter.  If so, and if the Pytyhon call 
ultimately feeds appropriate data to Tcl, the problem comes 
not from Python but one of Tcl, Win2000, or the chip, or the 
relationship between them.  If you are running current Python 
with current Tcl, the best we could do is add a warning to 
turn off Hyperthreading if strange errors occur, but I am not 
sure where.

I don't think I will do anything about this anytime soon, so
unassigning myself.

Will close unless OP provides more feedback or someone else can confirm.
