[OpenSIPS-Devel] Problem found while testing dialog profile

[Julien Chavanton]

One option would be to increment by 0 using a memcached_increment and use
the return value, this way we keep the atomic feature provided by memcached.

However this would break the cachedb abstraction since we would not use a
normal "cdb_func.get" but a cdb_func.add "0"

dialog profile -get-> | cachedb |  memcached

Cachedb specific feature like increment may not be easily abstracted.
