As a recent issue showed, sharing a cursor in a multi-threaded environment is not safe. The issue stems from asyncio not playing nicely in such environment. Moreover, this also leads to a confusion on query result retention - if several queries run at the same time it's not deterministic which query's result will be stored (also its success status). Therefore the best practice is not to share cursors at all.
