Add read(), write(), and readwrite() helper functions to shorten poll
functions.  Use get() instead of try/except KeyError for lookup.
XXX How could the lookup ever fail?

Remove module-level DEBUG flag.

Use iteritems() instead of items() when walking the socket map.

Reformat the functions I touched so that are consistently Pythonic.

entries on OS9 (where they are never available, and simply disabling
them might lead people to think otherwise).

Upped the stack size to 256KB. test_class ran afoul of the 64K limit, and this is probably a better fix than lowering the recursion limit.

GUSI/Threading interaction, I'm not sure, but I don't have the time to fix this right now.

rewrapped: as usual with my files everything was far wider than 80 chars.

This adds two new functions to mimetypes:
guess_all_extensions() which returns a list of all known
extensions for a mime type, and add_type() which adds one
mapping between a mime type and an extension.

encodes the triplets, while the latter adds optional charset and
language arguments.

the header is missing.

Restart the execution server with a clean environment and execute the
active module from scratch upon activation of Run/F5.

Add functionality to PyShell.py to restart the execution server in a new
subprocess.  The server makes a connection to the Idle client which sends a
block of code to be executed.

Modify ScriptBinding.py to restart the subprocess upon Run/F5, assuming that
an execution is not currently in progress.  Remove Import Module functionality,
not required now that the code is executed in a clean environment.

If the Debugger is active, also restart the subprocess side of the split
debugger.  Add functionality to RemoteDebugger.py to support this.

At this time breakpoints will be lost in the subprocess if Run/F5 is activated.
A subsequent checkin of PyShell.py will implement reloading of the breakpoints
into the subprocess debugger.  I'm keeping this separate as the design may
change.

The problem was that it expected rfc822.parseaddr() to return None
upon a parse failure.  The actual, documented return value for a
parse failure is (None, None).
