[Mono-dev] Patch to HashSet (System.Core) to enable serialization

I'm kind of stuck with adding support for this. After looking at
the .net binary serialization of their HashSet via a hex editor, it
seems that they only store:
Now, these are directly translatable into some of the internal structure
of the Mono implementation of the HashSet, however, if serialized this
way we lose information about the "Link" structure along with which
slots are empty and so forth. I'm guessing that loss of such information
would lead to an unstable deserialized version?
So, the question is, would it hurt that I add this information to the
serialized output (empty_slot, links, etc.)? Will the .net
implementation just ignore these extra fields?
