php - Zend Auth locked session

i nearly frustrated with how Zend handling session.

here is my case. i write a auth plugin that always check the the user credential utilize Zend_Auth. and when invoke hasIdentity function from zend auth, it will automatically start the session.

and the problem come when i have a long process that i need to execute. the session will lock the request until request completed. i try to release the lock by invoke Zend_Session::writeClose(false), so another request can be executed. but no way for me to start the session again.

is it a bad implementation if i try to resume stoped session?

there is only one session from the start until request execution ended?

thanks.

ps : i can do a little hack here. at the end of auth plugin i write a native php function (session_write_close) and if any controller need to use session again, i start it again with (session_start).
