-/* A technical note regarding our thread-local-storage (TLS) implementation:
- *
- * There can be up to TLSMAP_SIZE independent TLS keys in a given process,
- * though the first TLSMAP_START keys are reserved for Bionic to hold
- * special thread-specific variables like errno or a pointer to
- * the current thread's descriptor.
- *
- * while stored in the TLS area, these entries cannot be accessed through
- * pthread_getspecific() / pthread_setspecific() and pthread_key_delete()
- *
- * also, some entries in the key table are pre-allocated (see tlsmap_lock)
- * to greatly simplify and speedup some OpenGL-related operations. though the
- * initialy value will be NULL on all threads.
- *
- * you can use pthread_getspecific()/setspecific() on these, and in theory
- * you could also call pthread_key_delete() as well, though this would
- * probably break some apps.
- *
- * The 'tlsmap_t' type defined below implements a shared global map of
- * currently created/allocated TLS keys and the destructors associated
- * with them. You should use tlsmap_lock/unlock to access it to avoid
- * any race condition.
- *
- * the global TLS map simply contains a bitmap of allocated keys, and
- * an array of destructors.
- *
- * each thread has a TLS area that is a simple array of TLSMAP_SIZE void*
- * pointers. the TLS area of the main thread is stack-allocated in
- * __libc_init_common, while the TLS area of other threads is placed at
- * the top of their stack in pthread_create.
- *
- * when pthread_key_create() is called, it finds the first free key in the
- * bitmap, then set it to 1, saving the destructor altogether
- *
- * when pthread_key_delete() is called. it will erase the key's bitmap bit
- * and its destructor, and will also clear the key data in the TLS area of
- * all created threads. As mandated by Posix, it is the responsability of
- * the caller of pthread_key_delete() to properly reclaim the objects that
- * were pointed to by these data fields (either before or after the call).
