[Python-Dev] tstate->curexc_type etc

[Christian Tismer]

Hi friends,

in new Stackless, I saved
tstate->exc_type/value/traceback and
tstate->curexc_type/value/traceback

before switching to adifferent tasklet, and
restored that one's.

Under PythonWin, I saw crashes due to dangling
references through that, which vanished when
I increfed the exc_/... things. Problably they
were multiply reset.

But anyway, I even don't planto allow for
multiple exceptions in parallel at all, so
maybe I can drop this code completely.

What I again and again do not understand,
please help me out:
Why is there this double set of variables,
and which one should be preserved if at all
between tasklet switches?

many thanks - chris
