Luaproc is one of the multi-thread implementation for Lua. Compared with other lua multi-thread implementation, it provides several interesting features. See this paper: http://www.inf.puc-rio.br/~roberto/docs/ry08-05.pdf , which is written by the big names of Lua commnunity.
Recently, I want to rewrite the multi-thread module for one of my project to support the distribution computation. After considering several lua multi-task implementation ( LuaTask, luaproc, lane etc ), I decided to use luaproc as the base to build my module. However, I found that luaproc do not provide the interfaces to manage the life cycle of lua processes. After calling luaproc.newproc(), the only thing I can do is waiting for its end. I even can not identify a process, because there is no identifier for lua process. Since the management of process life cycle is very important for my module, I modified luaproc to support these requirements. Two new functions were added to both of the parent process and child process.
