Guys, take a look please, once time permit. Comments are welcome!
v29:
- rework test into luaform
- drop fine-grained locks idea since it requires too much code churn,
instead lets fence out a big code parts
v30:
- addess commenst (redundant code modifications due to more general
locking scheme)
- leave `latched` status for transactions which are started to
process (ie entered limbo processing) but not yet complete due
to WAL stalls, since I need to test exactly such state
- extend the test
