Process wait() should check PID has not been reused

...so that we don't wait on another process' PID.
Note that Process class guarantees this security only for "sensitive" methods 
such as kill(), send_signal(), etc..
Other methods (basically all get_* methods) doesn't have such guarantee.

It turned out it's wiser to avoid the PID reuse check on Windows as per 
revision e305df5644c3 .
