Re-meuh (French version). That's partially a problem of this patch
because all those flags get reset. I think that it would be cleaner
to replace all those boolean flags with just a simple bits16 or such,
making the flag cleanup reset way cleaner, and less error-prone if
more flag types are added in the future.
