Destroys a jss::concurrent_map instance and all contained
objects.
~concurrent_map();
Destroys every contained object. Destroys *this.
Nothing.
The destructor of a jss::concurrent_map
instance must not run concurrently with any other member functions
called on the same object. Users must ensure (through the use of
external synchronization) that the completion of any calls to member
functions on the same object happens-before
the invocation of the destructor.
