// Test the killCursors command.
//
// @tags: [
// # The test runs commands that are not allowed with security token: killCursors.
// not_allowed_with_signed_security_token,
// # Does not support stepdowns because if a stepdown were to occur between running find() and
// # calling killCursors on the cursor ID returned by find(), the killCursors might be sent to
// # different node than the one which has the cursor. This would result in the node returning
// # "CursorNotFound."
// does_not_support_stepdowns,
// uses_testing_only_commands,
// # This test relies on find commands returning specific batch-sized responses.
// assumes_no_implicit_cursor_exhaustion,
// # Time series collections (as views) have specific limitations on aggregation stages (e.g. $merge, $out) or cursor options (e.g. noCursorTimeout, singleBatch).
