/**
 * coroutine - Co-routines
 *
 * This code has helper functions for implementing co-routines, that
 * is, explicit co-operative context switching.  It's intended to
 * provide similar functionality to ucontext, but with a cleaner
 * interface.  At the moment this is implemented in terms of ucontext,
 * but the hope is to add other implementations for platforms that
 * don't have ucontext in future.
