Summary: Crash on "exit" when resources are low

Initial Comment:
This is another try in hope that you're able to reproduce.

Environment: Win7 with latest thread2.7b1, Tcl 8.5.11 MinGW build and ActiveState (when package 2.6.7 is replaced with 2.7b1);

It doesn't crash when using thread2.6.7.
It crashes only when resources running low, for this I also have reported a tracker here:
https://sourceforge.net/tracker/?func=detail&aid=3461049&group_id=10894&atid=110894

In the example I'am trying to create 10tsd entries whereas it stops earlier without error message. Of course 10tsd entries is weird but I'am having similar troubles in my own application on exiting and there I've got only two toplevels and ~10 entries but lots more itcl classes. So that's why I'am thinking it might be some resources ...

Source the attached main.tcl and in the console type:
> threads
which starts a few threads trying to ping in background. Then type:
> entries
which tries to create 200 toplevels but stops at 192. Then type:
> exit
it should crash now.

... I really hope that this time it works ...
thx
