Various function calls used can raise a Lua error (i.e. longjump). 
For example, lua_getglobal could raise if an __index metamethod on _G 
raised.  lua_pushstring could conceivably raise on memory alloc 
failure.  These possibilities are documented via the [-o, +p, x] 
designations in the reference manual.

As to what should be done about this, I guess it depends, and it might 
be ok if this is intended as part of the interface.  Personally, I 
like the C API but would be interested in one of the higher-level 
wrapper if it doesn't get in the way or sacrifice flexibility/correctness.
