Re: Unveil makes PHP behave strange with "Primary script unknown" errors

You really need to be able to do fairly low level debugging if you want to
use this stuff in a high level language like php

For pledge/unveil you need to take into account everything that might be
needed by the PHP process (for the script you're running or *any other
script* that is run afterwards in the same process)
