I agree that Thread.stop() should be not used in standard operations.

But I still advise using lock-free queues, especially in high load and 
highly multi-threading applications. Such structures does not need to 
synchronize, so no thread will wait for other thread, resulting in 
boosted performance.

Ans such highly multi-threading application can benefit from Thread.stop().
For example, lets assume application use MapReduce, and governing 
thread/computer detects that one of threads works too long (other 
threads/computers already finished same work). It may be error in code 
or hardware malfunction that cause infinite loop.
In such case governing thread will use Thread.stop() to kill misbehaving 
thread.
