[FX.php List] No GC (Garbage Collection) in IIS installation

Jonathan,
For permissions on Windows/IIS, usually the only IIS account that needs write/delete access to the temp folder is the anonymous access user account (the name starts with 'IUSR_'). I have also seen the 'Network Service' group mentioned as being needed in some cases.
If I remember correctly, the trailing slash is not needed, but if included it does not seem to affect path resolution (the system must ignore two slashes together).
Lack of outcry over the problem probably stems from many things: they don't use IIS (Linux/Mac seems quite popular in the FX.php demographic), site is not as busy, they otherwise haven't noticed (error logs, what error logs?), they don't use sessions, they do a custom set-up where they've explicitly assigned permissions, or used another temporary path with the required permissions (ie: Zend installations).
