DRIVERS-1447:
To work around a server issue, 2362d1a adds guidance on how to set limit and batchSize. TL;DR: if limit is set to the same value as batchSize, a higher batchSize MUST be sent to avoid an open cursor on the server. Note that despite this, the server may yield a cursor if not all results fit in the command response due to size limitations.

It is suggested to combine this work with DRIVERS-3009.
