This test aims at catching API misbehaviour w.r.t. the interaction
between interrupts and memory accesses, such as the bug fixed in
27f347e6a1
(accel/tcg: also suppress asynchronous IRQs for cpu_io_recompile)
Because the condition for triggering misbehaviour may not be
deterministic and the cross-section between memory accesses and
interrupt handlers may be small, we have to place our trust in large
numbers. Instead of guessing/trying an arbitrary, fixed loop-bound, we
decided to loop for a fixed amount of real-time. This avoids the test
running into a time-out on slower machines while enabling a high number
of possible interactions on faster machines.
The test program sends a single '.' per 1000000 loads/stores over the
serial. This output is not captured, but may be used by developers to
gauge the number of possible interactions.
