I don't see a mechanism in there where I can save a transaction off to the
side, to be picked up later by a different process or thread.

Hmm. And I recall you posted a question about "how long is 'long'?". Not
gonna go find it. Basically, I'd like to open a transaction, process some
operations (that occur over multiple HTTP requests; therefore, over multiple
processes/threads), and then commit/abort the transaction.

The operations would look something like:

    persistable_id = svn_fs_persist_txn
        ... ops ...
    } repeat

The sequence will be serialized, but will occur across multiple
threads/processes. As a result, the transaction ID needs to be an "int" oor
some kind, or a blob of bytes, either of which I can persist to a file.
