I agree. I wasn't addressing that problem. You described two separate
memory leaks in March. I was simply pointing out that one was fixed
correctly in 3.3.1.

Tcl_FinalizeThread does some other things besides calling thread exit
handlers. It would be nice to actually call it.
Since FreeDataBlock is used to free all the Tcl TLS blocks, we could
have FreeDataBlock detect whether Tcl_FinalizeThread has been called,
and call it if it hasn't been.
