-"""This test case provides support for checking forking and wait behavior.
-
-To test different wait behavior, override 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
