//  lldb::mutex_t           The native mutex type for mutex objects on the host system.
//  lldb::thread_t          The native thread type for spawned threads on the system
//  lldb::thread_arg_t      The type of the one any only thread creation argument for the host system
//  lldb::thread_result_t   The return type that gets returned when a thread finishes.
//  lldb::thread_func_t     The function prototype used to spawn a thread on the host system.
