Hi Paul, I have checked in bonsai code base, and there is no reference to should_close_asyncio_loop. It looks like a tornado thing.
However, looking at the full error trace, I can see that: > ldapwhoami: unrecognized option -� > Issue LDAP Who am I? operation to request user's authzid > > usage: ldapwhoami [options] > Common options: > -d level set LDAP debugging level to `level' > -D binddn bind DN > [...] Which may cause the tests to be aborted early and cause should_close_asyncio_loop to be accessed[1] before it is defined[2] in tornado.
