Anyone know what bit 4 is in the flags2 field on the SMB header?

My book has bits 3,4,5 and 7,8,9,10 as being "reserved". That's probably
based on the SNIA docs as well as source code from Samba and jCIFS.
It's possible, I suppose, that Windows systems just ignore these bits and
that there is no behavior associated with their being set. I'm interested
in finding out otherwise as a couple of people working on implementations
have sent me queries over the last few months.
