# This test used to assume the big libpcp mutex is recursive ...
# but this is no longer the case (as of Jan 2019), so the nested lock
# tests now fail with "Resource deadlock avoided" (lock-lock) or
# "Operation not permitted" (unlock-unlock) rather than succeeding.
# The test cases with nested unlock or lock operations will return an
# error and the filter is required if libpcp is built with
# BUILD_LOCK_ASSERTS defined.
