- * Requirements:
- *
- * 1. The thread safe mechanism should be lightweight so the library can
- * be used by non-threaded applications without unreasonable overhead.
- *
- * 2. There should be no dependency on a thread engine for non-threaded
- * applications.
- *
- * 3. There should be no dependency on any particular thread engine.
- *
- * 4. The library should be able to be compiled without support for thread
- * safety.
- *
- *
- * Rationale:
- *
- * One approach for thread safety is to provide discrete versions of the
- * library: one thread safe, the other not. The disadvantage of this is
- * that libc is rather large, and two copies of a library which are 99%+
- * identical is not an efficent use of resources.
- *
- * Another approach is to provide a single thread safe library. However,
- * it should not add significant run time or code size overhead to non-
- * threaded applications.
- *
- * Since the NetBSD C library is used in other projects, it should be
- * easy to replace the mutual exclusion primitives with ones provided by
- * another system. Similarly, it should also be easy to remove all
- * support for thread safety completely if the target environment does
- * not support threads.
- *
- *
- * Implementation Details:
- *
- * The mutex primitives used by the library (mutex_t, mutex_lock, etc.)
- * are macros which expand to the cooresponding primitives provided by
- * the thread engine or to nothing. The latter is used so that code is
- * not unreasonably cluttered with #ifdefs when all thread safe support
- * is removed.
- *
- * The mutex macros can be directly mapped to the mutex primitives from
- * pthreads, however it should be reasonably easy to wrap another mutex
- * implementation so it presents a similar interface.
- *
- * Stub implementations of the mutex functions are provided with *weak*
- * linkage. These functions simply return success. When linked with a
- * thread library (i.e. -lpthread), the functions will override the
- * stubs.
