   OBSOLETE_FORMS_CALLS), and 2.3.

/* A half-hearted attempt has been made to allow programs using this
 * module to exploit parallelism (through the threads module). No provisions
 * have been made for multiple threads to use this module at the same time,
 * though. So, a program with a forms thread and a non-forms thread will work
 * fine but a program with two threads using forms will probably crash (unless
 * the program takes precaution to ensure that only one thread can be in
 * this module at any time). This will have to be fixed some time.
 * (A fix will probably also have to synchronize with the gl module).
