Comment 10 for bug 2042744

Yeah, I got the same problem.

After a search in the source code, I guess it's something wrong with
monkey-patching the threading python library with the eventlet package. (which
is removed in the Newtown release according to the comments in the source.)

I try the following , but to no avail:

sudo -u keystone keystone-manage --standard-threads db_sync

The --standard-threads option is supposed to disable the monkey-patching, but it
doesn't seem to work....

I guess it's something wrong with the code in the sql.py ? I can still see
eventlet server being used in that file....😭
