Unfortunately, there is no clean way I see to hook this up from the vte
object. We can (and will) have more than one vte object opened at a
time, but the semantics of signalfd make it impossible to deliver each
SIGCHLD to its rightful owner without complicating things.
[ From what I tested:
- If you have two signalfd's listening to the same signal, they will be
dispatched in some round-robin manner.
- Also, if more than one child exits before we read signalfd (possibly
beloging to different terminals), they will be compressed to one
event. ]
We therefore need to do the reaping from a central location, and need to
remember to copy this snippet over to main.c in the future.
