Major changes to the interactive repl:
...
- We can now redefine imported identifiers.
- We can now use let-syntax, letrec-syntax, and modules at
top-level.
Hand-wavey Repl Semantics:
- Imported identifiers mean what they meant previously. In
particular, you cannot set! imported identifiers.
- An imported identifier may be redefined using define. Once
something is defined at the top-level, a specific location for it
is created, and all definitions, references, and set!s to that
variable go through the top-level location.
- Re-importing an identifier shadows the top-level location.
- Redefining re-exposes the top-level location.
- and do on.
- A reference to an unbound variable also fabricates a top-level
location for that variable.
Let's see how this goes.

3ce6d037e4
Fixed a bug in module imports where some marks were missing in action.

(Note from Kent, extracted from chez scheme release notes, follows)
This always worked:
(let ()
(define-syntax from
(syntax-rules ()
[(_ m v) (let () (import m) v)]))
(module a (x) (define x 'x-of-a))
(from a x))
Didn't work before this change:
(let ()
(define-syntax x-from-a
(syntax-rules ()
[(_) (let () (import a) x)]))
(module a (x) (define x 'x-of-a))
(x-from-a))

3. &lexical-position:
file-name: *stdin*
character: 7
Now:

Added tcp-connect-nonblocking which is line tcp-connect but puts the

socket in nonblocking mode. An operation that would block now
raises (continuable) a condition of type &i/o-would-block which
contains the port in question. There's no way to handle the
condition gracefully yet.

4f0a816295
Added a tcp-connect procedure that takes a host name and a service
...
name (e.g. "www.google.com" and "http") and returns two binary ports:
the first for output and the second for input.
Both ports must be closed for the connection to close.
Also added an example in lab/tcp-connect-example.ss which connects
to an http server, sends "GET /\n" and prints the responde.

6eb6bf750d
Added a (process "cmd" "args" ...) procedure that execs cmd, passing

args to it, and returns 4 values:
* the process's pid
* the process's standard-input-port (for writing)
* the process's standard-output-port (for reading)
* the process's standard-error-port (for reading)
See lab/process-example.ss for a sample usage.

Change of strategy in the garbage collector.
...
Previously: when a generation (say 2) is collected,
everything in gen 0 moves to gen 1
everything in gen 1 moves to gen 2
everything in gen 2 moves to gen 3
Now: when a generation (say 2 again) is collected
everything in gen 0 moves to gen 3
everything in gen 1 moves to gen 3
everything in gen 2 moves to gen 3
So, some objects get a leap from young to old if they're lucky to be
in the right time.
Consequences: when an object is moved by the collector, we don't
need to track old->new pointers and masks because all moved objects
are clean now. This both simplifies the collector and makes it more
efficient and might open the door for further optimization
opportunities. For bootstrap time, we get about 5% overall
saving and about 20% GC-time saving. Not bad.
