Re: Blind shot

Could you please ask Falko what he thinks ?
If this is not possible I'll have to find another solution to our 
workflow system, because it is mandatory that we have a multi-thread 
system (you see, if we have 3 tasks we do not want to wait for one to 
finish if we can execute them at pararell). All I would need was to bind 
the newly crfeated thread to the ongoing transaction (just like it was 
an inheritance).

Could you please help ? I'm getting stucked :(
