Ok, here is another try. This patch includes both the Xid cache
rewrite, source documentation (removed the big comment in xact.c and
added a README file), htup.h comments updated, and some user
documentation.
BTW, the overflow bit is certainly a better approach than the negative
cache. I am not sure about locking w.r.t. the XidCache though.
Please take a look at it.

Maybe there's lots of data loss but the records of data loss are also lost.
