Detailed Description

template<class Pad = bm::pad0_struct>
class bm::spin_lock< Pad >

Spin-lock with two-phase acquire (read + cas) padding parameter optionally adds a buffer to avoid CPU cache line contention.

TODO: test if padding realy helps in our case

Generally spin_lock does not have advantage over std::mutex but in some specific cases like WebAssembly it may be better due no "noexcept" property
