persistent-data/data-structures/bloom_filter.cc:10: error: integer constant is too large for 'unsigned long' type
Signed-off-by: Mikulas Patocka <mpatocka@redhat.com>
We had a cycle from transaction_manager <-> space_map, and also from
the ref_counters back up to the tm.
This prevented objects being destroyed when various programs exited.
From now on we'll try and only use a shared ptr if ownership is
implied. Otherwise a reference will be used (eg, for up pointers).
