   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>

  20 Functions that use static data and may still need locking:

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