No, your example has a bug. :-)

This function keeps an explicit reference to a tasklet which is
involved in the later pickling. This one works:

def capture():
     last = getcurrent()

Aside from that, I'm really not so happy with the solution to
"forbid pickling of current", but I haven't found a reasonable
alternative, yet. maybe allowing the pickle, but making it

kind regards -- chris
