This yields a warning, because "Flags" is not an integer value but a
structure.

Please avoid trailing whitespace, here and elsewhere.

Given that HttpServerTimeoutsProperty actually affects the behaviour of
the server in visible ways, I think using FIXME instead might be a good
idea.

This structure has inconsistent spacing.
