[Zope-dev] Speed win in Python's urllib.quote

While profiling a page full of dynamically-generated links, I was
interested to see Python's 'urllib._fast_quote' show up quite high in
the total time list.  After looking at it, I have found a pretty huge
speed win available, posted to Python's SF tracker as bug #1285086:


https://sourceforge.net/tracker/index.php?func=detail&aid=1285086&group_id=5470&atid=105470

Zope makes *heavy* use of urllib.quote (quoting each element of the path
in 'absolute_url', for instance), which makes it a particularly
interesting speedup for us.

I'm attaching the speed test and the patch, for consideration by the
Zope development community:  if this is enough of a win, we might
consider including a patched urllib in Zope2/Zope3 (or monkey-patching
urllib.quote).

Tres.
