Benoît Minisini 6950a075f0 [INTERPRETER]
* BUG: Tasks do not inherit signal handler pipe anymore, they recreate it instead. Otherwise you have interferences with the parent process of the task, and some signals are lost.
* BUG: Buffered streams now take the internal stream flag "available_now" into account. No idea why that was disabled.
* BUG: Standard streams now set the internal stream flag "available_now" if they are not connected to a terminal. Which may not be necessarily accurate, so it is a temporary change.
