I'm not sure how you can possibly read 
that way.  That post isn't even from a GC implementor and says nothing 
about implementation issues!

I think that post presents the strongest argument I know against the 
"use GC to reclaim your non-memory resources" argument, and the summary 
is that while that approach looks promising at first glance in practice 
it leads to resources not being reclaimed when they should be because 
the GC is not aiming for whatever sort of resource management those 
particular resources want.
