But they include an assumption.
The query is: are async writes and reads sequential? The
two specific cases are;
1) Are all reads that are initiated in time after a write
guaranteed to occur after that write has taken affect?
2) Are all writes that are initiated in time after a write (x)
guaranteed to occur after that write (x) has taken
I could also appreciate that there may be a difference between
the top/user layer view and the xlator internals .. if there is then
can you please include that view in the explanation?
Late night coder ..
