Verify that that cursors weakly hold request, and work if request is GC'd

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".

Create 1000 cursorRequests and check their results in otherRequestSuccess().

Verify that results of openCursor requests can be accessed lazily.
gc()
Ensure requests are not released if cursors are still around.

Ensure requests are not released if they are pending.
