Thanks, I was just hoping abort was a (currently undocumented) exception to this :)

Would it be possible/feasible in the future to bring MDB_NOTLS support to read-write transactions? (or at least some partial NOTLS support for only e.g. abort)

Motivation: Ability to abort "later" (e.g. at garbage collection in some languages).. as this "later" stuff does not necessarily happen on the original thread.

Hi,

The documentation for mdb_txn_begin() says "A transaction and its cursors must only be used by a single thread, and a thread may only have a single transaction
at a time.".

Does this also hold for mdb_txn_abort() for read-write transactions? I.e. does the abort also have to happen on the same OS thread as all the previous things
(begin, put, etc.)?

Calling mdb_txn_abort() requires passing the txn as a parameter, which looks pretty suspiciously to me like "using" it. Is this really a serious question?
