On POSIX and Windows threads, the creation API has configuration
parameter.  Thread.new doesn't have.

Two possible solutions.

1. raise ThreadError
2. wait for thread run and exit.

On second solution, it is easy to understand that the thread created by
Thread.new without procedure (block or parameter) start and stop
(Thread#wait) immediately.

But I prefer 1.
