      Description

      WT wants to enforce that RTS take exclusive access on a table to remove any unstable updates to avoid producing inconsistent results with a cursor operation that operates in parallel to it. With that enforcement, we get the following failure from some of the MDB tests.

      [j0:s0:n0] | 2021-07-06T02:17:35.057+00:00 E  STORAGE  22435   [BackgroundSync] "WiredTiger error","attr":{"error":16,"message":"[1625537855:57609][7280:0x7f6701201700], file:_mdb_catalog.wt, txn rollback_to_stable: __rollback_to_stable_btree_apply, 1518: file:_mdb_catalog.wt: unable to open handle, error indicates handle is unavailable due to concurrent use: Device or resource busy"}

      [j0:s0:n0] | 2021-07-06T02:17:35.057+00:00 F  -        23094   [BackgroundSync] "\n\n***aborting after fassert() failure\n\n"

      This ticket is to find out to close all open cursors before calling WT RTS API?
