Yes, I noticed it. There is a number of them. I looked carefully to 
lua.cc and tolua-generated sources, found one leak in LUA script, but 
really didn't find anything to eliminate those malloc and realloc leaks. 
Is it possible that LUA engine itself leaks? Valgrind also states a few 
leaks in SDL and X libraries, so anything is possible, I think.
