* If you add a new test, please do this if applicable.

* (7) Threads are created with a reduced stack size, for sanity checking.
|

* Therefore, it's important not to allocate huge buffers on the stack.

* When run with no arguments, ztest runs for about five minutes and

* produces no output if successful. To get a little bit of information,
|
||||
* specify -V. To get more information, specify -VV, and so on.
