help tcl problem

[francesco.grillo at ciaolab.com]

Hi to all ,
i have a blocking pb .
I use python 2.3 with tk/tcl 8.4.7 under windows2000;i wrote an application
that in the begining
under window systems was very instable , frequently crashed now and then
without a reason .
I found out that recompiling the tcl / tk libraries with "TCL_THREADS=1"
flag
these instability went away . Unfortunatelly there is a side effect that
is :
Memory allocation grow each time a call to tk is done .
Since my application heavly use tk and is supposed to stay on days and days
without shuting down , what it happens is that, after a while the memory
used by
applications is increased by Megas .
Below i wrote a very simple .py that demostrates how is easy to grab memory
from the system just calling the bell method in an infinite loop .

Thank for the help , Francesco Grillo
