The setcontext/getcontext will be much worse than setjmp/longjmp. The are more platform specific than longjmp. And they don't work well inside signal handler, just like longjmp. When I was working on HotSpot JVM, we had some problems with getcontext. They work 99.99% of time. We added many workaround for the .01% cases. I believe the Solaris guys have been improving the code. I am not sure of the current status. Hong
