Subject: Re: C extensions: disable GC for a Ruby object and enable GC later for it

rb_gc_disable() & rb_gc_enable() works global

but i use an hash for storeing, mark them with rb_global_variable.

and then i add the VALUE objects like this in the hash:


VALUE obj;
rb_hash_aset(global_evthandler,INT2NUM(obj),obj); #protect from GC

rb_hash_delete(global_evthandler,INT2NUM(obj));# unprotect

(as you can see i use the 'object-ID' for the hash key)
