# BF-BF conflict on MDL locks between DDL and delete query

#
# If bug is present, expect the wait condition
# to timeout and when the DELETE applies, it
# will be granted a MDL lock of type SHARED_READ
# for table t1. When resumed, the DROP TABLE will
# also try to MDL lock t1, causing a BF-BF conflict
