Hi, Sebastian. I like this idea, it would be specially useful for
table struct tests (eg ws2_32) and functions that are called more than
once for different tests (eg rsaenh). Each maintainer/helper could
slowly update the tests as they think it fits and new tests could
start benefiting from it. I hope more people join this conversation as
it clearly took a long time to produce the patch and letting it drop
from the list without talk would not be nice ;-)
