This is a port of coxpcall, a wrapper that preserves normal Lua error handling behavior when using coroutines.
* http://silentbicycle.com/ports/coxpcall-1.13.0-port.tgz It's a tiny library in pure Lua, and is mostly relevant as a new dependency for coming updates to luacopas and luasocket, as well as some new ports. Tested on amd64, please test and commit. Scott
