Summary: Allow generating multiple nested read transactions
from a write transaction

Hello,
I have a feature request. Would it be possible to read a database from the
point of view of a non-yet-committed write transaction?
What I want to do is to write a lot of entries into a database, use a couple of
threads to read those entries (using MDB_NOTLS) to generate a lot of new
entries (that will be written to disk and then once the generation is done,
drop the read-transaction handles and write (with MDB_APPEND) those new entries
from disk into LMDB.
This would have been possible if I had committed the first entries, but
unfortunately, it is impossible. I need to do this in the same transaction.
Have a great day,
kero
