We have custom stack expansion checks that it turns out are extremely badly tested and contain bugs, surprise. So add some tests that exercise the code and capture the current boundary conditions. The signal test currently fails on 64-bit kernels because the 2048 byte allowance for the signal frame is too small, we will fix that in a subsequent patch.
