- * WARNING: the overhead of POSIX ucontext is very high,
- * assembly versions of libco or libco_sjlj should be much faster
- *
- * This library only exists for two reasons:
- * 1 - as an initial test for the viability of a ucontext implementation
- * 2 - to demonstrate the power and speed of libco over existing implementations,
- *     such as pth (which defaults to wrapping ucontext on unix targets)
- *
- * Use this library only as a *last resort*
