java – Thread.yield()仍然是一个跨平台的雷区？

A hint to the scheduler that the current thread is willing to yield its current use of a processor. The scheduler is free to ignore this hint.

Yield is a heuristic attempt to improve relative progression between
threads that would otherwise over-utilise a CPU. Its use should be
combined with detailed profiling and benchmarking to ensure that it
actually has the desired effect.

It is rarely appropriate to use this method. It may be useful for
debugging or testing purposes,where it may help to reproduce bugs due
to race conditions. It may also be useful when designing concurrency
control constructs such as the ones in the java.util.concurrent.locks
package.
