php_session_initialize() now aborts an already-active session (closing the save handler) before reopening it, so session_reset() no longer calls open() twice with no close(). Sibling audit: php_session_start() returns early while a session is active; the strict-mode create_sid fallback leaves the close to the existing php_session_reset_id() failure guard, which already calls php_session_abort(); the rfc1867 update/cleanup callbacks are covered by the same new guard.

php_session_initialize() could run with a session already active, through session_reset() or rfc1867 upload progress, invoking the save handler open() again with no intervening close(), leaking the first handler instance and breaking userland handlers that track state per open/close pair. The initialize path now aborts via php_session_abort(), which closes the handler, before reopening. php_session_start() already returns early while active, and the strict-mode create_sid fallback relies on the php_session_reset_id() failure guard. A new test asserts the open/read/close/open/read sequence.
