i can't think of one.  the stack warning is given at a predetermined
value.  you can't lower it to get a warning sooner.  however, you
could start running your "heavy i/o" and get the results from sysrq-t.
DEBUG_STACK_USAGE will show the min free stack on each thread.  this might
point someone in the right direction.
