To elaborate a bit, anything that has been allocated with talloc,
can usefully serve as a talloc context itself. Usually structs 
that have members that need to be allocated are good candidates
for this usage scheme: when you TALLOC_FREE the outermost struct ptr
all the allocated members will be freed along with it.
This is commonly used in samba code.

Cheers - Michael
