The thin kernel intercepts interrupts to ensure that the non-real-time kernel cannot preempt the operation of the thin kernel.
瘦内核截取中断以确保非实时内核无法抢占瘦内核的运行。
Solutions to this problem require additional system calls in which the UTS explicitly asks the kernel to preempt KSEs. This is expensive.
解决这个问题，UTS为了抢先KSE，需要额外的系统调用去查询内核得到准确的KSE优先级。这样的开销很大。
Maskable interrupt sources that cannot preempt the kernel code and are thus able to invoke operating system APIs from within their handlers.
正规中断。不能抢占内核的掩码中断源，因此可以在处理程序中调用操作系统API。
Maskable interrupt sources with the ability to preempt the kernel code and thus have a lower latency and are less subject to jitter, see Response Time and jitter.
可以抢占内核的掩码中断源，因此拥有更短的延迟时间并且不容易受抖动，参考响应时间与抖动。
