/* Implements thread-local variables, which are all combined into one
   big table.
   
   When thread-local variables are not needed, this file doesn't
   declare them. Instead, declarations marked with
   THREAD_LOCAL_DECL() are used.

   When thread-local variables are needed, then THREAD_LOCAL_DECL()
   expands to nothing, and this file defines each thread-local variable
   as a field in one big record. The record is accessed through a single
   thread-local variable or through pthread_getspecific().

   Choose the names of thread-local variables carefully. The names are
   globally visible, and macros to redirect uses of thread-local
   variables can create trouble and poor error messages from the C
   compiler if the same name is used for a local variable. */
