module startup problem in 5.1

I see very serious problem un current module registration/startup
functions in 5.1.
In 5.0, there was a function zend_startup_module which did two things:

Register PHP module with the system
Run startup function of the module

Now, in 5.1 those functions got spearated. However, the problem is that it
now looks like this:

ZEND_API int zend_startup_module(zend_module_entry *module)
{
TSRMLS_FETCH();

 if (zend_register_internal_module(module TSRMLS_CC) == SUCCESS &&
     zend_startup_module_ex(module TSRMLS_CC) == SUCCESS) {
     return SUCCESS;
 }
 return FAILURE;

}

The trouble here is that zend_register_internal_module stores module in
internal hash as value, so when zend_startup_module_ex is run, it runs not
on the value in the hash but on original value. This leads to
module_started being never set in the hash value on module which was added
in runtime - meaning its destructor is never called on shutdown.

Since zend_register_internal_module never returns the hash value, I see no
easy way to fix this, but I think it must be fixed ASAP.

Hi Stas,

We can reimplement zend_register_internal_module() to return
zend_module_entry* instead of bool.

(The same behavior is in dl() function).

Thanks. Dmitry.
