Some points:
- gdome is not thread safe. while using it in a threaded environment,
I've found some bugs, one of them is creating singletons. I fixed the
one that did hurt at that point, but it was not making it thread safe,
instead I reordered the instructions so it would leak, but not crash.
Anyway, this shouldn't be the case, since the singleton is just
created once, and you may get no more than just few leaks (between:
'create singleton instance' and  'global = singleton-instance')
- gdome uses glib and libxml  and they do their own memory management
and do cache. You need to compile these with options like
--enable-gc-friendly and --disable-mem-pool, see Glib user guide and
look at 'running glib applications', something like 'G_SLICER'

then you need to recheck your tests. :-)
