Sure. I'm actually have a single client just doing a small contiguous

Both the memory request and file request structures are contig I think.
The total_completed isn't filled in during the write. I think it
happens also during the read (althought I'm not quite sure on that).
I'm using the HEAD CVS version, (just did an update this morning).
Avery,
can you send me your benchmark? One of our nightly tests is a
noncontiguous benchmark that writes small little 2k pieces out to a
file exercising {noncontig,contig} in {memory,file}, and that test has
been passing for a while now (since we fixed the immediate completion
for zero-length io case).
If you've found a bug, we'll have to beef up our noncontiguous and
small i/o test cases.
