If causes an assert failure on a DEBUG kernel, a shutdown on a
non-debug kernel. Either way, I'd prefer to leave it enabled as a
good reminder that we need to fix the damn bug (*) sooner rather

not sure it is the right fix.

I'm working on it at the moment, along with all the other allocation
things...
Cheers,
Dave.
