Got rid of our reliance on sleeps to ensure correct timing in the WebRequest debugger unit test. A change with a recent diff removed some of the races by waiting for the client to enter the busy state before sending an interrupt to mimic ctrl-c. Generalized that a bit, and extended it to ensure the initial handshake between the harness, debugger request, and the request to be debugged is correct. I've removed the 10s sleep on startup, and the 3s sleep after each notification from the various requests back to the harness. Also added a bunch of comments to hopefully explain the test better, and renamed some files/functions to better reflect what they're doing. This seems to work well on my box… I've run it a bunch in both dbg and opt builds to try to get it to fail but haven't yet. Fingers crossed ;)
HipHop VM for PHP
HipHop VM (HHVM) is a new open-source virtual machine designed for executing programs written in PHP. HHVM uses a just-in-time compilation approach to achieve superior performance while maintaining the flexibility that PHP developers are accustomed to.

HipHop is most commonly run as a standalone server, replacing both Apache and modphp.
