[PHP-DEV] Q: Writing *.phpt's: How to specify multi-process test?

Good Morning PHP Internals! I'm trying to get some unit test coverage on some functionality that requires two separate processes, and I'm wondering how to do this with a *.phpt. WinCache has a cross-process lock functionality that allows synchronization between two processes. (See:

[PHP-DEV] Q: What is the Config.w32 equivalent of PHP_ADD_MAKEFILE_FRAGMENT?

Internals folks-- I'm trying to add something...complicated to a PECL extension, and I need to add some custom dependency rules to the Makefile. Specifically, I'm compiling a manifest file using 'mc', which produces both a .h file and a .rc file. I need to ensure the 'mc' command runs before

PHP Internals folks-- We're doing some performance work in WinCache, and we're finding that some frameworks are...uh...enthusiastically using file_exists(), is_file() and is_dir() functions on files/directories that don't exist. Every. Single. Pageload. Does the PHP stat cache include
