Ok, I'll try and send a patch with this change only.
BTW  xinfo  is 32 bit long, but I think only 2 bits are used right now?
I think I can make it a 8 bits, and add another 8 bits for nrels,
nsubxacts, and nmsgs and the new thing. That should save
another 2 bytes, while leaving space for extention. Or we can make
it a 8 bits only, but only 2 bits would be left "empty" for future
extentions; I don't know if we care about it...
