`cursor.executemany` does not work as expected

[gijzelaerr]

did you check the db api?

https://www.python.org/dev/peps/pep-0249/#executemany

Use of this method for an operation which produces one or more result sets constitutes undefined behavior, and the
implementation is permitted (but not required) to raise an exception when it detects that a result set has been created by
an invocation of the operation.

as described in the standard, we do this with .exectue() under the hood for pymonetdb.

The second issue described is strange and require investigation.

I did, but it seems I fail at reading... :)
