Hi,
I saw this in zend_opcode.c zend_cleanup_class_data():
/* Note that only run-time accessed data need to be cleaned up,
* pre-defined data can not contain objects and thus are not probelmatic */
Which lead me to look into zend_declare_property() and I noticed that
you cannot declare properties that are objects/arrays/resources. Is
there a good reason for disallowing extension authors to do that?
Alternatively, do you suggest using zend_hash_update() on class
properties even though I really need this property to be static so its
shared by all instances of the class?

The problem is that objects and resources can't really stay alive in
between requests because those mechanisms are shutdown at rshutdown. Arrays
also can't stay alive because they need to be emalloc()'ed or they won't
work with the engine. I think it'd be quite complex to change this behavior
and the work around probably needs to be in the extension depending on how
bad it is to recreate these or somehow cache them for rinit.

properties even though I really need this property to be static so its

If these are per-request statics it can probably be solved.

How could it be solved?

I rememer seeing a patch that gave anything that was allocated (either
malloc or emalloc or whatever_alloc) a destructor function pointer alias
free. Wouldn't that solve any related problem?
