Hrm. Something does seem very wrong then. Why does Richard's always seem
to occur in the same place, though? The rest of these reports seem
arbitrarily distributed. 17068 worries me too: either some logical is
*very* subtly wrong, or there's a bug that scribbles over allocation
metadata (but not other memory?) in such a way as to cause delayed GC
failures.
