Appears that test/recovery is hung in jenkins.
Looking at the traces this appears to be a deadlock between an eviction and checkpoint thread (threads 34 and 10 respectively in the attached dump).
From my quick dive, this looks to be related to the PASS_LOCK added as part of
WT-2664 and an evict worker not yielding this lock while in a loop waiting for the handle lock held by the checkpointing thread.
