It'd be a bug if it was, as setReachable() for GcResource
check a cached _reachable flag before invoking
markReachableResources which in turn will call the
PropertyList::setReachable.

It'd be also easy to end up in infinite loop if this wasn't
the case.

What may throw some water on the fire here would be invoking
the GC iteration less often. Currently the heuristic as for
when to go checking is based on number of GcResource allocated
since last run. This is 50 by default and can be changed
with the GNASH_GC_TRIGGER_THRESHOLD environment variable.
