changes for CancelAction with the test->tests checkin.  Undo this.

(Also in DummyEngine.py, but there I screwed up the undo, so it will

Reworked version of rev 1.49. Fixes a strange problem with the re module in Python 2.1c1. Works now with the official 2.1 release

the standard Python 2.1 distribution. The asyncore module from
the Medusa package has been removed it is not compatible with the

tables.

pack(): Fix a slight misunderstanding of the semantics; if an object
isn't pointed to by root object (i.e. the magic \0\0\0\0\0\0\0\0 oid),
then it's current record doesn't keep it alive.

checkCreateWithFilename(), checkCloseDoesUnlink(), checkDel(): Don't
unlink explicitly, but assert that the file is unlinked after close.

BaseSetupTearDown.tearDown(): It's okay if the tear down unlink fails
because the file already doesn't exist.

suite(): Use makeSuite.

should be on close.  By default, we unlink the file unless we were
passed a file-like object, in which case we don't unlink by default
(because the client owns the file).

close(): Only close the file if the file isn't already closed.  Only
unlink if the default unlink flag is true, or we're explicitly told to
unlink via the argument.  This should fix the logfile turd problem.
