+"""This test case provides support for checking forking and wait behavior.
+
+To test different wait behavior, overrise the wait_impl method.
+
+We want fork1() semantics -- only the forking thread survives in the
+child after a fork().
+
+On some systems (e.g. Solaris without posix threads) we find that all
+active threads survive in the child after a fork(); this is an error.
+
+While BeOS doesn't officially support fork and native threading in
+the same application, the present example should work just fine.  DC
