* continuation-passing model in C which can be used as a
|

* ``callback''-like alternative to using a process context to
|

* tsleep() on an object address, waiting for some event or status
|
||||
* change on that object. Since ANSI C provides neither
|
||||
* lexically-nested functions nor heap allocation of activation
|
||||
* records, we implement a continuation as a struct containing:
|
||||
* 1. A function pointer, pointing to the continuation.
|
||||
* 2. A object pointer: the object being "slept" upon.
|
||||
* 3. An argument pointer: a pointer to private storage containing
|
||||
* other arguments to the continuation function, including any
|
||||
* additional state beyond the "slept-upon" object.
