"""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.
