The current python bindings do have a number of problems, which have
improved on the HEAD branch.  Those changes do improve startup time and
memory usage.

I was originally going to target these changes at gtk 1.2, but decided
instead to use them for the gtk 2.0 version after discussions with various
people.  The changes were quite extensive, and making things compatible
with previous versions would take a lot of effort.  That is why I have
left the 1.2 targeted branch with the current (sub optimal) architecture.

I suppose this is another vote for regular updates to the development
platform is a good thing.  It allows maintainers can phase out old
versions of libraries with architectural issues which can't be fixed
without breaking compatibility.

Just out of interest, are those times for startup only, or startup and
shutdown?

Some of the improvements in head pygtk come from having less python code
in the binding, and implementing more in the C extension.  This also
increases the number of pages that can be shared between processes.

sounds like the perl bindings are going really well.
