  27  * Most of these async callbacks get data that's held in thread-specific
  28  * memory (specific to the callback thread) that will be re-used by that
  29  * thread automatically on the next call - synchronous or asynchronous -
  30  * of the same routine.  For example, an async getpwnam call will use a
  31  * slot in the caller's thread-specifc data to save the returned struct passwd.
  32  * A subsequent call to getpwnam will release the previous entry
  33  *
  34  * Callers of getaddrinfo must free the returned addrinfo list using freeaddrinfo.
  35  * Callbacks for async getaddrinfo lookups must also free the returned addrinfo list.
  36  *
  37  * Callers of getnameinfo supply their own memory for the node and serv names.
  38  * Callbacks for async getnameinfo lookups get node and serv names that reside in
  39  * thread-specific memory that is reclaimed by the libraray.  The results must not be freed.
