Description
While investigating a test failure, Keith Bostic discovered that an LSM drop can return EBUSY, even if there are no user-operations happening on the LSM tree.
The EBUSY return happens if a work unit is being processed while a drop is attempting to get exclusive access to the LSM tree.

The relevant information from Keith Bostic in
WT-2418:Alexander Gorrod, what's happening here is that LSM drop can attempt an exclusive open while a worker is doing a queue operation. Here's the start of the __wt_lsm_tree_drop function:
/* Get the LSM tree. */WT_WITH_HANDLE_LIST_LOCK(session,ret = __wt_lsm_tree_get(session, name, true, &lsm_tree));WT_RET(ret);/* Shut down the LSM worker. */WT_ERR(__lsm_tree_close(session, lsm_tree));I'm not familiar with the LSM code, so I don't know what the right solution is.
What do you think about changing __lsm_tree_find, so if exclusive access is requested, we call something like __lsm_tree_close, to clear WT_LSM_TREE_ACTIVE and wait for WT_LSM_TREE.queue_ref to go to 0, before checking WT_LSM_TREE.refcnt?
Bloom filter creation is a queue task, which means we might spin for awhile, though.
