Not sure that does what I want.
It appears to allow some 'kill' actions to wake the process.
I'm sure I've looked at the 'hung task' code since 2007.

Ah, that was added in May 2015.
Not surprising I didn't know about it.

I'll leave the code doing:
set_current_state(signal_pending(current) ? TASK_UNINTERRUPTIBLE ? TASK_INTERRUPTIBLE);
for a while longer.
