If even a modest share of Boomer‑owned firms close instead of changing hands, the impact could run into the tens of millions of jobs and hundreds of billions in lost local spending and tax revenue over the coming decade, according to a report released last month by McKinsey. But the same wave represents a rare buying window: experts estimate there are regularly 10 million to 11 million small businesses for sale in any three‑year span.

So I went on an adventure to implement this new API. It was mostly about modifying the behavior of the mdb_txn_begin function, which was throwing an error when called with a parent transaction and the MDB_RDONLY flag simultaneously, allowing starting another nested read-only transaction even when the parent transaction must have been disabled, enabling multiple nested read transactions simultaneously. As you can see from the linked thread, I wasn't following C99 but rather C11, as I had to reimplement an atomically ref-counted (ARC) system to ensure that only the last dropped nested read transaction freed the allocations and was therefore using atomics. Unfortunately, the atomics APIs are only C11-compatible and require enabling extensions... I hadn't disabled the parent transaction when child read transactions were still alive because I was using my LMDB Rust wrapper: heed, which handles this issue via lifetimes. I finally implemented everything C users needed so that I could propose a well-working version of the nested read transactions feature.
