zee, andi -
in threded mode we access (atleast)
EG(uninitialized_zval_ptr) before it's initialized ->
BadIdea(tm)
what happens is that (see assert.c as an example)
OnChangeCallback gets called by the ini-mechanism before the
executor is initialized.
but zval_ptr_dtor (used in assert.c-OnChangeCallback) checks
against EG(uninitialized_zval_ptr) - so calling zval_ptr_dtor
anytime before init_executor will cause an UMR.
i know that the startup-order is a very delicate thing so i'd
like to check with you guys first if you have any ideas..
