New submission from Morten Bentsen <[EMAIL PROTECTED]>:
The uuid module uses a single global buffer for storing random values
obtained from the system. This can (and does) cause non-uniqueness of
generated id's when using the uuid4 function in a multithreaded program.
The following snippet shows the problem - _buffer is the global buffer:
# When the system provides a version-4 UUID generator, use it.
if _uuid_generate_random:
_uuid_generate_random(_buffer)
return UUID(bytes=_buffer.raw)
