   3 Things that are still known to be needed for thread safety:

   5         none

  10 Things that might be nice, but are not required:
  11
  12         getnetent_r             <desired, but not required for SuSv3>
  13         gethostent_r            <desired, but not required for SuSv3>
  14         getprotoent_r           <desired, but not required for SuSv3>
  15         getnetbyname_r          <desired, but not required for SuSv3>
  16         getnetbyaddr_r          <desired, but not required for SuSv3>

  22 Functions that use static data and may still need locking:
  23
  24
  25         --------------------------------------------------------------------
  26
  27         libc/inet/rpc/rpc_thread.c:
  28
  29         __rpc_thread_variables is currently disabled, since thread
  30         local storage seems to not be correctly specified as
  31         weak functions.
  32
  33         --------------------------------------------------------------------
  34
  35         unistd/getpass.c:
  36
  37         static char buf[PWD_BUFFER_SIZE];
  38
  39         getpass                 <fix required>                          <---
  40
  41         NOTE: This function returns a pointer to a static data structure.
  42         This seems like it requires an _r version of this function.  Glibc
  43         does the same thing.  Oops!  So much for thread-safe glibc!
  44
  45         --------------------------------------------------------------------
  46
  47         unistd/sysconf.c:
  48
  49         static long int ret_vals[_UCLIBC_SYSCONF_NUM_VALID_ARGS];
  50
  51         find_or_add_in_table    <fix required?>                         <---
  52         main                    <fix required?>                         <---
  53
  54         NOTE: I'm not sure if this needs to be made reentrant...
