- * This is a reimplementation of a subset of the pthread_getspecific/setspecific
- * interface. This appears to outperform the standard linuxthreads one
- * by a significant margin.
- * The major restriction is that each thread may only make a single
- * pthread_setspecific call on a single key.  (The current data structure
- * doesn't really require that.  The restriction should be easily removable.)
- * We don't currently support the destruction functions, though that
- * could be done.
- * We also currently assume that only one pthread_setspecific call
- * can be executed at a time, though that assumption would be easy to remove
- * by adding a lock.
