/**
\p Options are:
- - \p opt::lock_type - mutex type, default is \p cds::sync::spin
- - \p opt::back_off - back-off strategy, defalt is \p cds::backoff::Default
- - \p opt::allocator - allocator type, default is \ref CDS_DEFAULT_ALLOCATOR
+ - any \p cds::algo::flat_combining::make_traits options
- \p opt::stat - internal statistics, possible type: \p fcstack::stat, \p fcstack::empty_stat (the default)
- - \p opt::memory_model - C++ memory ordering model.
- List of all available memory ordering see \p opt::memory_model.
- Default is \p cds::opt::v:relaxed_ordering
- \p opt::enable_elimination - enable/disable operation \ref cds_elimination_description "elimination"
By default, the elimination is disabled.
