Sax buckets are actually not parser specific. I have no intention on
being multi parser, but I did not change them much when migrating from
expat to libxml2. 

I use apache memory for them for two reasons:
1. It is easy to avoid leaks, because apache has memory allocations that
will automatically be freed when the request is done and
2. I know how to use it.

So I will change my code so that xmlGcMemSetup is called safely. 

There is however one thing that worries me. If I have to take care for
libxml2 to not free memory passed into sax callbacks, this probably
means that on the other end I am leaking memory. Does libxml2 expect the
sax callbacks to take memory ownership?

Sincerely,
