would shift the GPL/LGPL "interfacing-issues" only one

Also interesting with regards to current ext3-behaviour was
the following one:
Kernel developers squabble over Ext3 and Ext4

And finally some new default-ext3-settings in the new kernel?

And could you please check the DB-Size before and after
such a typical "update-job" (so that we get an impression
about the transferred byte-volume - maybe you could also
give the count of new records in case of insert-jobs)?
And do you work over GBit-Ethernet (or an even faster
"NFS-
s good enough in
these typical, more ReadDirection-related-scenarios -
the currently implemented locking-scheme seems not all
that restrictive (if working against non-shared SQLite-caches) -
so I hope, the sqlite-devs (although they often recommend,
to work singlethreaded wherever possible ) keep up
ring).
Do you see any chance (since all writes are already
"centralized" if one uses the new async-writer-approach),
that in case of a running "granular-backup" we could
avoid our planned "workaround"?
In either case - that will be a nice addition to the engine -
