By including expat are we blessing it as somehow a better solution than
PySQLite *is* a better choice for inclusion than the others: because
the license permits, it's standalone, easy to use. and can be
reasonably included with binary distributions of Python (it can even be
linked statically into the extension). More or less any database
module that's not embedded (except for ODBC, perhaps) is on shakier
ground because the protocol can change between database versions,
though I suppose that's not expected to happen very often for something
like PostgreSQL. Also, MySQLdb is especially tricky because of the
I can't imagine how that rather contrived scenario could reflect badly
on Python or SQLite.. it certainly wouldn't be any worse than Python's
standard library support for networking or XML, or the interpreter's
inability to scale with threads.
