@corona10: I added the following sentences to the doc:

The API is not thread safe: a writer should only be used by a single thread at the same time.

PyBytesWriter_Finish:

The writer instance is invalid after the call in any case. No API can be called on the writer after :c:func:PyBytesWriter_Finish.

PyBytesWriter_Discard:

The writer instance is invalid after the call. No API can be called on the writer after :c:func:PyBytesWriter_Discard.
