Calling the function via lua_resume instead of via lua_call/lua_pcall is
required since it must be possible to yield from inside these functions.

This is for two reasons: if the function does something protracted,
I have it yield every so many opcodes to allow for cooperative
scheduling (using the opcode counting hook). Also, there is a custom
calling mechanism that uses yield/resume.
