When faced with a program that barely works because some threads aren’t getting enough CPU time relative to others, resist the temptation to “fix” the program by putting in calls to Thread.yield. You may succeed in getting the program to work after a fashion, but it will not be portable. The same yield invocations that improve performance on one JVM implementation might make it worse on a second and have no effect on a third. Thread.yield has no testable semantics.
