Thanks everybody for proposals.
Seems I found a solution - call lua_sethook() from different thread, if I
decided to terminate script execution (measured big CPU time consumption).
It's working in usual lua implementation.
But it's not working in luajit - hook is not called immediately after
lua_sethook() call in other thread, only at script end.
Example: http://pastebin.com/HdnfVQKB
Main question is: is there other way to interrupt lua_State from other
thread? Consistency of interrupted lua_State is not necessary but
preferred, I only need return from luaL_dostring() in main thread with
non-zero result.
