I think it does. Just off the cuff, we need a struct that has transfer
information -
struct transfer { void *buffer; int buflen; HANDLE *handles; int
handlecount;}; and a couple of virtual functions for the fd class -

transfer prep_transfer () const;
void complete_transfer (transfer const &);

Anyway, just my 2c.
