19    Description:
21    Changed the interface of structures Timer and Unix to match the most
22    recent Basis spec.
24    In the case of Unix there still seems to be an open/weird issue:
26       The {text,bin}{In,Out}streamOf functions are supposed to create
27       fresh streams whenever they are called -- as opposed to have them
28       return the same stream every time.  This design is supposed to
29       prevent space leaks caused by proc values hanging on to streams.
31       The reap function, on the other hand, is supposed to close the
32       streams.  This cannot be done without having a handle on the
33       stream in proc after all...
35    I took the liberty to implement the following stopgap solution:
37      The proc value hangs on to the most recently created stream(s).
38      Reap closes those.  If either or both of the two streams hadn't
39      been created at all yet, then reap will close the corresponding
40      file descriptors directly.
42    PS: I don't understand the original space leak argument anymore.  If
43    a proc hangs on to the imperative stream, then I/O operations on those
44    will advance the state of the cached stream and avoid the space leak.
