Threading libbson's data structures are not thread-safe. you are responsible for accessing and mutating these structures from one thread at a time. libbson requires posix threads (pthreads) on all unix-like platforms. on windows, the native threading interface is used. libbson uses your system's threading library to safely generate unique objectids, and to provide a fallback implementation for atomic operations on platforms without built-in atomics.
