Subject: Re: [PHP-DEV] Re: Windows OpCache bug fix
From: dmitry@zend.com (Dmitry Stogov)

Anatol committed a better fix. It falls back to file-cache in case of
failure, and maps just a small portion of SHM for synchronization between
processes.
In general, extending this approach, we may map the whole SHM segment into
different address space and implement routines to find/load data from SHM
instead of files. But this is for 7.1.

Thanks. Dmitry.
