Kevin Bates updated TOREE-437:
------------------------------
Description:
Whenever Toree is run in the background - either directly from the shell or
indirectly from the Jupyter stack that is started in the background - cell
interrupts (via ctrl-C or SIGINT from parent) are not received - resulting in
the inability to interrupt long-running cells.
This can be most simply demonstrated by invoking run.sh into the background
(e.g., run.sh &) then issue ctrl-C (or `kill -2 <pid>`) to no avail.
This is related to TOREE-33 but only pertains to cell interrupt functionality
since complete life-cycle management is assumed by the parent for the shutdown
(double ctrl-C) scenario.
