Fri Jul 14 17:38:54 CEST 2017
Fix #4751 by not allowing denomination deletion (GC)
to cascade into reserve_out table (and tolerating such
deletion failures). This way, denominations will be kept
around until the last reserve that references them (or
known_coins derived from them) is closed. Naturally, in
most case we expect reserves to be closed much faster
than DKs, so in practice this should rarely apply. -CG
Sun Jun 11 17:03:56 CEST 2017
Finish implementation and testing of automated refunding
of expired reserves (#4956). -CG
