----------------------------------------------------------------

Hi [~yonigo].

I did this:
# In Client I upserted some rows (with the mechanism above.)
# In Client I turned off autocommit.
# In Client I now upserted many more rows (again, using the UPSERT from above).
# Now in Client II I do a {{SELECT COUNT\(*) FROM test;}}

Now Client II will take a fairly long time to skip the uncommitted rows.
If you have an OMID patch I'm happy to try.
