tests: prevent busted from reloading the ffi module and others It turns out that Busted started cleaning the environment in 2.0rc5 as a result of Olivine-Labs/busted#62. This, in turn, caused the ffi module to be reloaded for each spec file, and LuaJIT doesn't appreciate it. The net effect is an assertion error in LuaJIT. By using the --helper feature of Busted, we can pre-load some modules ahead of Busted and prevent it from reloading them--making LuaJIT happy again. 2015-03-01 14:49:48 -05:00			`-- Modules loaded here will not be cleared and reloaded by Busted.`
