As is the case with all of LibCXXW's widgets, an
internal execution thread takes care of processing display server
events and updating the combo-box.
Instantiating a x::w::standard_combobox_lock acquires an internal
lock that blocks all other execution threads from accessing the
combo-box. Afterwards, x::w::standard_combobox_lock's
methods update the combo-box with a consistent snapshot of its
current contents, and state.
