The CHECK_FOR_INTERRUPTS call in gingetbitmap turns out to be inadequate to prevent a long uninterruptible loop, because we now know a case where looping occurs within scanGetItem. While the next patch will fix the bug that caused that, it seems foolish to assume that no similar patterns are possible. Let's do the CFI within scanGetItem's retry loop, instead. This demonstrably allows canceling out of the loop exhibited in bug #19031.
