Re: [jira] [Created] (CELIX-222) Memory used by libxml2 not released
at program close.
Hm this again looks like something that I don't like when looking at OSGi
and bundles..
Copying from the libxml2 docs [1]: "It's sometimes very hard to guess if
libxml2 is in use in the application, some libraries or plugins may use it
without notice. In case of doubt abstain from calling this function or do
it just before calling exit() to avoid leak reports from valgrind !"
So while I do see the problem, the leaks are a result of libxml, and as
such there is no memory that needs to be cleared during runtime, and I
don't think there is a risk of increasing memory during the lifetime of the
application.
So I'll look into the issue, and some nice solution that also includes the
curl init/destroy, but also going to give it a lower priority. If there is
a good reason for not doing this, please let me know.

I agree that this is a low priority thing (I gave it a priority of "Trivial" when creating it).
