Sandro,

Any particular GC technique you have in mind?

IMHO, one of possible and clean solution for this kind of issues in GEOS
is to apply GC in form of shared_ptr - smart pointer that controls
lifetime of objects and frees developers from knowing *when* an object
is/should be deallocated.

However, I'm not really sure if GEOS is ready for another revolution ;-)
