I'd stick to 0.25sec since it was solid for a week.
I don't think the race window is very large, we could even experiment
with a smaller delay, because debug kernels don't hit the issue. The
debug kernel can't be >0.1sec slower I reckon.
IOW I hope 0.25sec already has pretty solid safety margin?
As I mentioned last week - this is called almost 100 times by the test
so the longer delays will be quite visible in the test runtime.
